K Lock Nuts Feature Captive Free-Spinning Lock Washers That Turn Freely During Installation Until Contact Is Made With Mating Surface And Tightened.
K Lock Nuts are durably constructed with steel for long lasting reliability and strength. Fasteners offer one-piece solutions that save time over installing a separate lock washer and nut, and are locked in place when fully seated and tightened. Designed to be driven by a wrench or a pneumatic tool for ease of installation. Dimensions vary per model.
