Summit Racing™ Nord-Lock® Locking Washer kits

If you have a bolt that just won't stay torqued due to vibration, expansion, or other factors you might want to give Summit Racing™ Nord-Lock® Locking Washers a try. The wedge locking technology makes it impossible for bolts to loosen unintentionally. We package them in quantities of 4 or 10, and offer many common automotive sizes to select from.
