How to use

Select the correct wrench size matching the nut or bolt head. Position the open jaws securely over the flat sides of the fastener, keeping the wrench at the intended 15° angle when access is limited. Apply steady force, pulling the wrench toward you where possible to reduce slipping. For repeated or high‑torque work, verify that the wrench fits tightly and that the fastener is undamaged before use.

Recommendations

Inspect the wrench for wear or deformation before use; do not use if jaws are rounded or the tool is cracked. Use the correct size to avoid damaging fasteners. Store larger sizes by hanging on a pegboard when possible to protect the finish.
