AN3 Bolts -- Undrilled Head
AN3 bolts have a 10-32 UNF thread and a 3/16" diameter shank. All AN3 bolts have a 0.406 inch thread length regardless of grip length. This thread length is designed to be long enough for an AN365-3 or AN310-3 full-height nut plus one AN960-10 washer.
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, AN3-13A) indicates an undrilled head and an undrilled shank for use with a self-locking nut.
AN bolt nomenclature can be confusing. Please take a look at our page on Identifying AN Bolt Sizes.
