Our XPL^® lockbolt is the latest addition to the Howmet Fastening Systems lockbolt family. With a grip range that is more than twice that of other fasteners, each part may be used in more than double the applications. This means fewer part numbers to inventory. The wide selection of materials and diameters make the XPL^® the most versatile lockbolt system ever.

Our GP and LGP^® lockbolt families improve on NAS lockbolts by optimizing the lock groove design. This optimization makes the GP and LGP^® lockbolt systems significantly lighter than comparable threaded fastening systems.

Our HUCKCOMP^® lockbolts are high-strength, lightweight fasteners intended for use in composite material applications. The flanged titanium collar enhances joint integrity by spreading a high clamp load over a large area, reducing the bearing stress applied to the composite material.

Howmet Fastening Systems has a full line of NAS lockbolt standards produced to procurement specifications NAS621 and NAS1413. These standards include lockbolts in both shear and tension type configuration that are available in titanium, alloy steel, A286 CRES and aluminum alloy. There are two types: NAS shear lockbolt and NAS tension lockbolt.

Our LHP™ lockbolt is a high-strength, lightweight aerospace fastener intended for use in composite material applications. It is easily the most cost-effective aerospace fastener available for fastening composite material. The LHP can help reduce aircraft weight due to its all-titanium construction, and it improves fastener installation time due to its pull action tension/tension installation method.
