Inspect the tool for damage before use and avoid using cheater bars or extensions that exceed the tool’s intended capacity.

Usage recommendations

For prolonged life and reliable performance, keep the wrench clean and dry, store it indoors, and periodically check for wear or deformation. Use the correct size (7 mm) to minimize fastener damage and follow standard safety practices when working with hand tools.
