Product Description
The AN174-35 is a close-tolerance hex-head aircraft bolt with 1/4-28 UNF-3A threads designed for precision structural joints. This steel fastener installs in reamed holes for tight, interference-fit applications where standard bolts cannot achieve required tolerances. Commonly used in airframe shear joints such as control-surface hinges and wing attachments.
Installation requires torquing to specification followed by securing with a castellated nut and cotter pin per aircraft maintenance manual requirements. The precision body ensures proper fit in reamed holes without rework.
