How to use

Place the 17 mm hex end of the extended socket onto the nut or bolt head and apply steady torque using the L-shaped handle. Ensure correct seating on the fastener to avoid rounding. Use controlled force and, if necessary, a breaker bar or additional leverage for tightly torqued fasteners. After use, clean the tool and store it in a dry place to prevent corrosion.

Usage recommendations

For best results, select the 17 mm Proline CrV extended socket when you need extra reach in confined spaces. Inspect fasteners before use and avoid applying excessive impact force that may damage the tool or fastener. Regularly clean and inspect the socket for wear; replace if deformation or significant wear is observed.
