Aerospace Fasteners Market

Tariff relief written into a Commerce Department and USTR notice titled Implementing Certain Tariff-Related Elements of the U.S.-EU Framework (90 FR 46136, published 25 September 2025) means EU-made civil aircraft parts, rivets and bolts included, have paid only the most-favoured-nation duty since 1 September 2025, outside the Proclamation 9704 aluminum tariff. Aerospace fasteners are the bolts, pins, rivets, nuts, nut plates, screws, collars and inserts that join airframes, engines and interiors; the Aerospace Fasteners Market covers new-build OEM line-fit plus aftermarket and MRO demand across commercial, military, rotorcraft and space platforms. Douglas Insights sizes it at USD 8.14 billion in 2025, rising to USD 15.5 billion by 2035 at a revenue CAGR of 6.64%. The arithmetic: 1,393 Airbus and Boeing jet deliveries x USD 5.84 million of fastener revenue pulled per delivered jet = USD 8.14 billion. The study belongs to our aircraft systems and components coverage and follows the Douglas Insights research methodology.

Which companies supply aerospace fasteners after the CAM and TriMas Aerospace deals?

Howmet Aerospace leads aerospace fasteners with USD 1.75 billion of Fastening Systems sales in 2025, a 21.5% share of the USD 8.14 billion total on that basis. PCC Fasteners and LISI Aerospace follow, and two 2025 deals reshuffled the mid-tier of bolt and rivet suppliers.

Howmet reported Fastening Systems third-party sales of USD 1.75 billion in 2025 against USD 1.58 billion in 2024, up 10.7%, in its fourth-quarter results filed with the SEC. That segment also sells commercial transportation and industrial fasteners, so the 21.5% share is a ceiling. Howmet then closed its purchase of Consolidated Aerospace Manufacturing (CAM) from Stanley Black & Decker on 6 April 2026 for about USD 1.81 billion, according to its second-quarter 2026 Form 10-Q; Fastening Systems sales jumped 36.7% to USD 589 million in that quarter.

TriMas agreed on 4 November 2025 to sell TriMas Aerospace, the home of the Monogram, Allfast and Mac Fasteners brands, to an affiliate of Tinicum for about USD 1.45 billion in cash, roughly 18 times trailing earnings before interest, taxes, depreciation and amortization (EBITDA), as its SEC exhibit states. TriMas Aerospace sales reached USD 396.4 million in 2025, up 34.7%.

PCC Fasteners, part of Precision Castparts, runs SPS Technologies, Cherry Aerospace and Shur-Lok and machines titanium, Inconel 718 and A286 nut plates and self-retaining bolts. LISI Aerospace booked EUR 1.19 billion of 2025 revenue, about 70% of it in fasteners. Incora distributes aerospace hardware from 60+ locations with 644,000+ active SKUs. Douglas Insights estimates the top three (Howmet, PCC Fasteners and LISI Aerospace) hold 55.8% of 2025 aerospace fastener revenue.

Which aerospace fastener product type, from lockbolts to blind rivets, makes the money?

Bolts and pins make the money in aerospace fasteners, earning USD 3.14 billion or 38.6% of 2025 revenue, because titanium lockbolts and Hi-Lok style pins carry wing and fuselage joint loads. Rivets follow at 23.7%, with nuts and nut plates third.

Bolts and pins reach USD 6.13 billion by 2035 at 6.92% a year, since composite wide-body structure uses more titanium pins per joint than aluminum skins. Rivets hold USD 1.93 billion; solid aluminum rivets are cheap and hand-driven, so their 6.05% growth trails the market. Nuts and nut plates earn USD 1.46 billion and grow 6.71%, riding self-locking nut plate demand in access panels. Screws are the smallest named type at USD 764.7 million and 5.62% a year, held back by interior refurbishment cycles.

Collars, inserts and other parts are the fastest-growing aerospace fastener segment at 7.33% a year, from USD 846.1 million to USD 1.72 billion. Swaged collars pair with each lockbolt, and inserts fill thin composite panels, so this group gains share as wide-body output climbs.

Why are narrow-body rate ramps the biggest boost to aerospace fastener volume?

Narrow-body ramps add 1.85 points of the 4.40% annual volume leg in aerospace fasteners, because the A320 family and 737 together delivered 1,054 of 1,393 Airbus and Boeing jets in 2025. Wide-body recovery, defense and aftermarket pull supply the remaining 2.55 points.

Airbus delivered 793 commercial aircraft in 2025, up from 766 in 2024, 607 of them A320 family jets, and closed the year with a record 8,754-aircraft backlog, according to its full-year results of 19 February 2026. Airbus guides about 870 deliveries for 2026 and a rate of 70 to 75 A320s a month by the end of 2027. Douglas Insights counts that single-aisle ramp at 1.85 points of fastener volume growth a year to 2035.

Boeing delivered 600 airplanes in 2025, including 447 737s and 88 787s, as its fourth-quarter deliveries release of 13 January 2026 shows; it had delivered 348 in 2024, so output rose 72.4%. A 787 or 777 shipset carries far more titanium bolts than a 737, which is why Boeing wide-body recovery and the A350 rate-12 target for 2028 add 1.35 points to aerospace fastener volume.

Military aircraft, rotorcraft and launch vehicles add 0.70 points. Defense fasteners fall under the specialty-metals clause, so domestic suppliers with certified melt sources win those programs. The aftermarket and MRO channel adds the last 0.50 points: an in-service fleet that keeps growing needs replacement rivets and bolts at every heavy check, a link our Aircraft Line Maintenance Market study tracks from the hangar side.

Regional and business aircraft sit inside the defense and aftermarket points rather than adding a fifth driver. Embraer line-fit, business jets and rotorcraft each use smaller shipsets than an A320, so Douglas Insights folds them into the 0.70-point and 0.50-point legs instead of the jet count. Narrow-body jets still dominate fastener part counts: the A320 family and 737 made up 75.7% of 2025 Airbus and Boeing deliveries. Wide-body jets made up 17.7%, yet each one consumes far more titanium per shipset, which is why the 787 and A350 ramps matter more than their unit share suggests.

The four contributions, 1.85 + 1.35 + 0.70 + 0.50, sum to the 4.40% volume leg. Douglas Insights expects jet deliveries to rise from 1,393 in 2025 to about 2,143 by 2035 on that path, and the price leg of 2.15% a year sits on top.

Which engine, titanium and qualification hurdles slow aerospace fastener shipments?

Three hurdles remove 1.10 points from aerospace fastener volume in the slower case: late engines (0.50 points), titanium and nickel-alloy supply (0.35 points) and slow part qualification (0.25 points). Each one caps how many bolts and rivets assemble into jets.

Engines come first. Airbus blamed its A320 rate reset on Pratt & Whitney not committing to the engine volumes ordered, in the same full-year results release. Gliders parked without engines still consume fasteners, but they delay the next build slot; Douglas Insights removes 0.50 points of fastener volume for that drag in the slower case.

Raw material is the second hurdle, worth 0.35 points. Titanium alloys, A286 steel and Inconel 718 bar come from a handful of melters, and defense work demands domestic melt certification. Qualification is the third, worth 0.25 points: a new aerospace fastener source needs OEM approval part by part, so switching after the CAM and TriMas Aerospace ownership changes takes 12 to 24 months on our estimate.

Where is aerospace fastener revenue booked across North America, Europe and Asia Pacific?

North America books USD 3.60 billion, or 44.3% of 2025 aerospace fastener revenue, because Boeing, the defense primes and Howmet, PCC Fasteners and TriMas Aerospace plants sit there. Europe follows on Airbus final assembly and LISI Aerospace output.

North America grows 6.21% a year to USD 6.58 billion by 2035. Europe earns USD 2.54 billion in 2025 and grows 6.48%, helped by the 1 September 2025 return to most-favoured-nation duty on EU aircraft parts entering the United States under the 90 FR 46136 notice. Asia Pacific, at USD 1.43 billion, is the fastest-growing aerospace fastener region at 8.12% a year, because Airbus assembly in Asia, COMAC programs and new MRO hangars all add local fastener buying. Latin America takes USD 276.6 million and grows 6.90%, mostly Embraer line-fit and airline MRO. The Middle East and Africa hold USD 284.7 million and grow 5.27%; the wildcard is Gulf MRO, where wide-body heavy checks could lift rivet and bolt pull above that rate.

How much fastener cost rides on each delivered jet, and what do buyers pay per lockbolt?

Each delivered Airbus or Boeing jet pulls about USD 5.84 million of aerospace fastener revenue in 2025 across OEM line-fit, aftermarket, defense and space, rising to USD 7.22 million by 2035. Per-part prices span cents for rivets to hundreds of dollars for titanium bolts.

Douglas Insights puts realised prices at USD 0.05 to USD 0.40 for solid aluminum rivets, USD 4 to USD 25 for titanium lockbolts with collars, USD 8 to USD 60 for blind bolts, and USD 150 or more for large Inconel 718 engine bolts. Long-term agreements with OEMs reset prices every 3 to 5 years, often with metal surcharges. That pricing power shows in disclosed growth: Howmet Fastening Systems sales rose 10.7% in 2025 and LISI Aerospace revenue 15.6%, while Airbus deliveries rose 4%.

Douglas Insights models the price leg at 2.15% a year to 2035, below recent supplier gains because consolidation under Howmet invites OEM pushback. Distributors such as Incora add kitting fees on top, so MRO buyers pay more per aerospace fastener than OEM line-fit buyers.

Is the aftermarket and MRO channel a steadier aerospace fastener buyer than OEM line-fit?

OEM line-fit takes about 71.6% of aerospace fastener revenue in 2025 and aftermarket and MRO the other 28.4%, on Douglas Insights estimates; the aftermarket swings less because it follows flight hours, not build rates.

OEM line-fit volumes fell hard when Boeing output dropped to 348 jets in 2024, then rebounded to 600 in 2025, per its delivery release. Aftermarket and MRO fastener demand tracks heavy checks, structural repairs and cabin work instead. Our Aerospace Cabin Interiors Market report covers the seat and monument refits that draw on screws and inserts. Douglas Insights expects the aftermarket share to slip to about 26.9% by 2035 as new-build rates rise faster.

How do titanium, aluminum, steel and nickel alloys split aerospace fastener value?

Titanium carries about 47.2% of aerospace fastener value in 2025 on Douglas Insights estimates, against 21.3% for aluminum, 18.9% for steel and 12.6% for nickel alloys. Composite airframes need titanium because aluminum corrodes against carbon fibre.

Aluminum rivets still dominate part counts on narrow-body jets, but their low price keeps their value share small. Steel, mostly A286 and high-strength alloy bolts, serves landing gear and engine mounts. Nickel alloys such as Inconel 718 hold hot-section engine joints. The material split matters for tariffs: the steel and aluminum proclamations hit fastener inputs, unlike the titanium mill products that dominate value. A different mix shows in the Automotive Fastener Market, where steel dominates.

Which DFARS specialty-metal rules and tariff notices govern aerospace fastener sourcing?

Two US rule sets shape aerospace fastener sourcing in 2025: the Defense Federal Acquisition Regulation Supplement (DFARS) clause 252.225-7009 on specialty metals and the 90 FR 46136 tariff notice for EU aircraft parts. One governs defense melt sources, the other duties.

The DFARS 252.225-7009 clause (JAN 2023 version) treats titanium, zirconium and high-alloy steel, nickel and cobalt as specialty metals. Commercial fasteners escape the domestic-melt rule only when the maker certifies that at least 50% of its specialty metal bought for fasteners in the year is domestically melted. That 50% test favours US mills and keeps defense aerospace fastener lines in North America.

On trade, the September 2025 notice exempted civil aircraft and their parts from the reciprocal tariff and from Proclamation 9704 on aluminum when they come from the EU. Military aircraft parts are outside that relief. Douglas Insights treats the exemption as permanent in the base case, worth about 0.2 points of European price stability a year.

How would aerospace fastener revenue in 2035 shift if delivery rates slip or climb?

Aerospace fastener revenue lands between USD 13.2 billion and USD 17.5 billion in 2035 across our scenarios, against a base of USD 15.5 billion. The spread comes from Airbus and Boeing delivery rates, the engine supply drag and how far suppliers lift prices.

The base case runs 4.40% volume and 2.15% price for 6.64% revenue growth. The slower case cuts volume to 3.30% and price to 1.60%, giving USD 13.2 billion, if engine shortages persist and the CAM integration triggers OEM price pushback. The faster case lifts volume to 5.30% and price to 2.50% for USD 17.5 billion, with A320 rate 75 met in 2027 and Boeing 737 output climbing.

Sensitivity: an extra point of jet delivery growth adds about USD 1.55 billion to the 2035 aerospace fastener total. Published forecasts run from about 4.70% to 7.50% a year; our 6.64% sits in the upper half because Boeing output rebounded 72.4% in 2025 and Howmet closed the CAM purchase on 6 April 2026, as its Form 10-Q notes.

Douglas Exclusive: the Aerospace Fastener Shipset Pull Index

The Aerospace Fastener Shipset Pull Index is a Douglas Insights model built from 18 inputs. It uses 8 delivery counts by aircraft family from Airbus and Boeing, 4 fastener-content weights we assign by airframe size, and 6 supplier revenue figures from Howmet, LISI Aerospace and TriMas. It weights each 2025 delivery by fastener pull.

Weights are 0.55 for the A220, 1.00 for the A320 family and 737, 2.10 for the A330 and 767, and 2.60 for the A350, 777 and 787. The 1,393 deliveries convert to 1,711.8 index units. Wide-body jets were 246 deliveries, 17.7% of the count, yet they generate 35.4% of weighted pull, or about USD 2.88 billion of aerospace fastener revenue.

The finding: fastener revenue tracks wide-body output, not headline delivery totals. The supplier inputs agree: Howmet Fastening Systems grew 10.7% (SEC filing), LISI Aerospace 15.6% and TriMas Aerospace 34.7% in 2025, all far above Airbus delivery growth of 4%. Douglas Insights reads the gap as wide-body mix plus pricing, and the index flags the A350 and 787 rate plans as the swing factor for bolt and pin demand.

What methodology converts 1,393 jet deliveries into aerospace fastener revenue?

The methodology multiplies 1,393 Airbus and Boeing deliveries in 2025 by USD 5.84 million per delivered jet to reach USD 8.14 billion. It then grows units 4.40% and price 2.15% a year to USD 15.5 billion in 2035.

The model counts 24 countries across 5 regions and uses 31 data points: 8 family delivery counts, 2 Boeing annual totals, 6 supplier revenue figures, 4 published growth rates, 4 content weights, the CAM and TriMas Aerospace deal prices and 5 regional assembly weights. Cross-check one: the three disclosed fastener revenues (Howmet USD 1.75 billion, LISI Aerospace fasteners near EUR 832 million and TriMas Aerospace USD 396.4 million) equal roughly 38% of our total, consistent with a top-three share of 55.8% once PCC Fasteners is added. Cross-check two: published 2025 base-year estimates run USD 7.8 billion to USD 9.4 billion, and USD 8.14 billion sits inside that band, within 5.4% of the midpoint.

What should aerospace fastener buyers and suppliers watch through 2027?

Three aerospace fastener signals matter through 2027. They are Airbus reaching 70 to 75 A320s a month, Boeing sustaining 2025 delivery levels above 600 jets, and OEM contract resets after Howmet folded CAM into Fastening Systems in April 2026.

Watch Fastening Systems quarterly sales: the 36.7% jump to USD 589 million in the second quarter of 2026, reported in Howmet’s Form 10-Q, includes CAM, so organic growth needs stripping out. Watch whether Tinicum keeps the Monogram and Allfast brands independent. And watch the specialty-metals 50% domestic-melt test if titanium sponge stays tight. A two-point slip in Airbus single-aisle output cuts aerospace fastener volume by about 0.4 points a year.
