SKF introduces its lug lock device, a mechanism designed to alert fleet maintenance personnel of a loosened wheel nut before it backs off the stud. The SKF lug lock provides a timely flag when a nut is in need of re-torque. The SKF lug lock is constructed with flexible slits that allow it to slip onto the nut while maintaining the ability to tightly grip the OD of the nut, ultimately leading to a complete install in minutes. The SKF Lug Lock fits virtually all two-piece wheel nut systems commonly used on trucks, buses and trailers. The lug locks are available in a 60-pc. bag (No. LL33MM) and 20 bags of 60 pieces, totaling 1,200 in point-of-sale barrel (No. LL33MMB).
