SKF’s Lug Lock device is designed to alert fleet maintenance personnel of a loosened wheel nut before it backs off the stud, providing a timely warning when a nut is in need of re-torque. The 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. The slip-on locks interconnect with the hub-piloted wheel to provide a visual alert of a loose wheel nut that needs tightening. Additionally, the lug lock helps maintain the proper wheel nut torque to allow the tires to run truer, leading to reduced fuel consumption.
Manufactured of a premium-grade polymer, the lug lock resists water, road salt and debris to withstand harsh environments. The lug lock fits virtually all two-piece wheel nut systems commonly used on trucks, buses and trailers and are available in a 60-piece bag (part number LL33MM) and 20 bags of 60, totaling 1,200 in point-of-sale barrel (part number LL33MMB).
