How to use

Select the appropriate contact or setting on the wrench that corresponds to the fastener size and measurement system required. Position the wrench securely on the nut or bolt head, apply steady force while maintaining alignment, and turn in the required direction to tighten or loosen. For best results, ensure fastener heads are clean and the wrench contact surfaces are fully engaged to avoid slippage. After use, store the wrench in a dry place to limit corrosion and maintain performance.

Usage recommendations

Use appropriate personal protective equipment when working with hand tools. Avoid excessive force beyond the tool's design to prevent damage to fasteners and the wrench itself. Periodically inspect for wear and clean contacting surfaces to ensure consistent grip and safe operation.
