Product Description

The AN174-31A is a hex-head aircraft bolt with 1/4-28 UNF-3A threads and an undrilled shank, conforming to Aeronautical Standard specifications. This close-tolerance fastener is engineered for precision shear joints in landing gear torque link assemblies, where exact fit and load distribution are critical. Installation requires selecting the correct -31A length per the aircraft's Illustrated Parts Catalog and torquing per the maintenance manual specifications.

The bolt's undrilled design eliminates the need for safety wire in applications where shear loads dominate tensile loads.
