How to use

Select the wrench size that matches the fastener head to ensure a correct fit. Place the open-end or ring end over the nut or bolt and apply steady, controlled force in the required direction to tighten or loosen. For higher torque and reduced rounding risk, position the ring end fully over the fastener when possible. Keep the wrench aligned with the fastener axis and avoid side loading. After use, clean off dirt and store the wrenches in their holder or toolbox to prevent corrosion and damage.

Usage recommendations

When working on rusted or seized fasteners, apply penetrating lubricant first and use gradual force to avoid damaging the wrench or fastener. Do not use combination wrenches with extensions or cheater bars; these tools are intended for manual use to maintain safety and prevent tool deformation.
