Overview

Fabricated from steel and cadmium plated per QQ-P-416A, Type II, Class 3. AN310 castle nuts are used with drilled-shank bolts, clevis bolts, eye bolts and studs. The slots in the nut accommodate a cotter pin for safety purposes. The thinner AN320 castellated shear nut, with half the tensile rating of the AN310 nut, is used with clevis bolts and threaded taper pins which are subject to shearing stress only.
