How to use

Select the wrench size that matches the nut or bolt head. Place the open jaws fully over the fastener so the load is taken by the flats, not the corners. Use steady, controlled force to turn the fastener; with the 15° jaw set, reposition the wrench as needed to continue turning in tight spaces. Store the wrench on a peg or in a tool board using the hanging hole when not in use.

Recommendations

Do not apply impact force or use the wrench as a hammer. For corroded or seized fasteners consider using appropriate penetrating lubricant first. Inspect the wrench for wear or damage before use and replace if jaws are deformed to maintain safe and accurate operation.
