View Catalog Page in PDF format

AN8 bolts have a 1/2-20 thread with a 1/2" shank diameter. All AN8 bolts have a 0.680 inch thread length regardless of bolt length. This thread length is designed specifically to allow the use of a full-height nut plus one AN960-816 flat washer.

Grip Length refers to the length of the unthreaded portion of the shank. Grip lengths are available in 1/8" increments to match the thickness of the materials being bolted together (the threaded portion should never be positioned inside the hole). If your assembly is between sizes, select the next longer bolt and use additional AN960-816 and AN960-816L washers to take up the slack.

A or no A? AN bolts were originally designed to be used with a castle nut and cotter pin, so the base part number indicates a drilled shank. The addition of an "A" at the end (for example, AN8-13A) indicates an undrilled shank for use with a self-locking nut.

UHL: Under Head Length (also known as Full Shank Length or Overall Length not including bolt head)

AN bolt nomenclature can be confusing. Please take a look at our page on Identifying AN Bolt Sizes.

Comments about AN8 Airframe Bolt, 1/2-20 Thread:

Airframe bolts seem to be consistently true to size. These micrometer out pretty close to the 1/2 diameter. Not much play when used in bushings.
