AN10 bolts have a 5/8-18 thread with a 5/8" shank diameter. All AN10 bolts have a 0.955 thread length regardless of grip length. This thread length has been calculated to be sufficient for a full-height nut plus one AN960-1016 washer. Sold individually, nuts and washers sold separately. Torque AN10 bolts to 92-108 lb-ft with AN365 or AN310 full-height nuts, or 50-65 lb-ft with AN364 or MS21042 half-height nuts. 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.
