How to use

Select the wrench with the correct metric size for the fastener to ensure a secure fit and avoid rounding. Use the open end for quick turning in tight spaces and the boxed end when higher torque or a firmer grip is required. Position the boxed end fully over the fastener head for even load distribution and apply steady force; reverse direction and re-seat the tool as needed to prevent slippage. Store the set in its holder or toolbox after use to keep sizes organized and protect the tool edges.

Usage recommendations

Always match wrench size precisely to the fastener, inspect tools for wear or damage before use, and avoid applying impact forces unless the tool is rated for such use. Use appropriate personal protective equipment and follow standard safety practices for mechanical and automotive work.
