Product Description
The AN174-17A is a close-tolerance hex-head bolt designed for interference-fit structural joints in aircraft airframes. Manufactured from steel with a 1/4-28 UNF-3A thread, this bolt provides precision fit in reamed holes where standard clearance fasteners are insufficient. The undrilled shank (denoted by the "A" suffix) prevents accidental fastener rotation during installation.
Commonly used in landing gear attachments and critical structural connections, it requires installation in a close-fit hole and torque application per AC 43.13-1B specifications. Conforms to AN close-tolerance standards for aerospace applications.
