AN9 Airframe Bolt, 9/16-18 Thread

Click for a larger picture of AN9 Airframe Bolt, 9/16-18 Thread

AN9 bolts have a 9/16-18 thread with 0.9063 inch thread length. Torque AN9 bolts to 67-83 lb-ft with AN365 or AN310 full-height nuts. Torque them to 40-50 lb-ft with AN364 or MS21042 half-height nuts.

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, AN9-37A) indicates 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.
