F-35 Lightning II Titanium Fastening System is not something you notice at an air show, but without it the jet does not leave the tarmac. When you stand on the Lockheed Martin flight line at Fort Worth and hear the F-35 spool up, thousands of Howmet fasteners are quietly doing their job.
Howmet’s titanium hardware on the F-35
Howmet Aerospace supplies a wide range of aerospace fasteners in titanium and other alloys for modern military aircraft, including the F-35 Lightning II. The company’s fastening systems cover hi-locks, collars, pins, bolts, and specialty engineered fasteners designed for composite and titanium structures.
Defense industry coverage notes that Howmet is a key supplier of fasteners and engineered components to the F-35 program through its participation in Lockheed Martin’s industrial base. These titanium fasteners help secure major structural joints and skin panels where high strength-to-weight ratios and corrosion resistance are critical.

What makes these fasteners stand out
Howmet’s titanium fastening systems are engineered primarily for weight savings and durability in extreme flight conditions. Titanium offers a high strength-to-weight ratio and outstanding corrosion resistance, which is crucial for an aircraft that may operate in salty marine environments and high humidity. On the F-35, this material helps the jet meet demanding performance and stealth requirements without excess weight.
The fasteners are designed to work with advanced composites and metallic structures, keeping tolerances tight and minimizing micro-movements that could lead to fatigue over thousands of flight hours. Stand near an F-35 during maintenance and you see rows of flush fastener heads along the fuselage and wing skins; every one is part of the broader fastening strategy that keeps the airframe stiff and quiet in the air.
US defense demand and production scale
In Howmet Aerospace’s latest filings, CEO John C. Plant highlights defense and aerospace fastening systems as a core growth area as global fleets expand and age. The F-35 program, led by Lockheed Martin, is expected to produce more than 3,000 jets worldwide over its life, with the United States as the largest customer. That long production tail supports a steady flow of titanium fastener orders to suppliers like Howmet.
Beyond new-build aircraft, the F-35 Titanium Fastening System benefits from maintenance and overhaul cycles. Fasteners in critical areas are periodically inspected and replaced, creating recurring demand for high-spec hardware during depot maintenance events. For an investor, this means the hardware you never see can turn into a multi-decade revenue stream tied to the global F-35 fleet size.
From engineering design to flight line
Design engineers at Howmet work closely with airframe manufacturers to match fastener geometry, coatings, and installation methods to the F-35’s mixed-material structures. That includes countersunk and flush designs for stealth-sensitive surfaces where protruding hardware could disrupt radar signature, as well as robust fasteners for internal load-bearing joints. The focus is on predictable behavior under repeated high-G maneuvers and thermal cycling.
On the ground, maintainers need fasteners that can be installed and removed without damaging expensive composite panels or titanium frames. Howmet’s fastening systems incorporate features to reduce galling and thread wear, and they are supported with technical documentation and torque specifications to keep installations consistent across bases. Walk through a hangar and you can spot tool trays marked specifically for these fasteners, a reminder of how standardized they have become in F-35 maintenance practice.
Broader context and Howmet stock
Howmet Aerospace is a diversified engineered products manufacturer supplying aerospace fasteners, turbine components, and structural parts across commercial and defense fleets. The F-35 Lightning II Titanium Fastening System sits inside its larger aerospace fastening segment, benefiting from US and allied defense procurement and long-run sustainment spending. For US investors, this hardware is one of the quiet levers behind steady aerospace revenues.
Howmet Aerospace stock (NYSE: HWM) reflects that mix of commercial and defense exposure, with titanium fasteners for the F-35 forming one of several long-duration defense programs supporting its balance between cyclical air travel demand and more stable military contracts.
