How to use

Select the 14 mm open box wrench and position the open jaw squarely on the nut or bolt head. Apply steady force to the handle in the required direction to tighten or loosen the fastener, keeping the wrench fully seated to avoid slippage. For stubborn or corroded fasteners, apply penetrating lubricant and allow time to work before attempting to turn. Avoid excessive impact or using the wrench as a hammer; if higher torque is needed, use an appropriate larger tool or a torque wrench to prevent damage.

Usage recommendations

Inspect the wrench before use for visible wear or deformation. Use the tool only on the specified 14 mm fasteners and avoid overtightening. Store the wrench in a dry toolbox to maintain the corrosion-resistant finish and prolong service life.
