AN5 bolts have 5/16-24 UNF threads and a 5/16" diameter shank. All sizes of AN5 bolts have a 0.531 inch thread length, regardless of grip length. This thread length has been designed specifically to accommodate a ms210425 ms nut 5/16-24 and one AN960-516 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).
