How to use

Select the wrench with the correct jaw size for the fastener to avoid rounding. Place the open end fully onto the nut or bolt head so the load is applied across the flats. Apply steady force, pulling the wrench toward you when possible for better control. For stuck fasteners, use gradual force and avoid sudden jerks; do not use wrenches as hammers or extend handles with pipes.

Usage recommendations

Inspect wrenches before use for wear or damage. Keep the chrome finish clean and dry to maintain corrosion protection and store the set in a tool roll or toolbox to preserve fit and surface quality.
