Materials & care

Wipe wrenches clean with a dry cloth after each use to remove oil, grease, and debris. Store in a dry environment to prevent moisture exposure. The mirror chrome finish provides rust and corrosion resistance, but occasional light oiling of the surface will further extend tool life.

How to use

Select the correct wrench size for your fastener using the high-visibility stamped markings on each tool. Position the open end securely onto the bolt or nut, ensuring full contact. Apply steady, even pressure—the four-point contact system will distribute force to prevent slippage. Always wear protective gloves and eyewear when performing heavy-duty mechanical repairs.
