It secures dual wheels to the hub using a 3/4"-16 UNF-2A thread, serrated shank, and a stepped body diameter. The left-hand thread is used on the driver's side of the vehicle to prevent lug nuts from loosening due to wheel rotation. It fits Meritor, Budd, and Trailmobile axles, commonly used on TK, TKL, RL, TL, RN, RQ, and TKN series, and is a Grade 8 fastener for strength and durability.
