Gardner Bender designed the innovative locknut wrench to end frustration. Specifically developed for tightening and loosening locknuts this wrench features a thin profile that makes those normally tight spaces a thing of the past. It can be used to loosen or tighten a locknut by rotating the wrench in the direction of the arrows clearly etched into both ends of its sturdy steel construction. A specialty hooked tip latches onto the locknut and maximizes turning leverage. The Gardner Bender locknut wrench is a reliable and durable addition to any tool box.
