How to use

Replace the worn or damaged joint piece by disconnecting power from the tool and removing any retaining components that secure the existing coupling. Align the 19 mm square profile of the replacement joint piece with the mating square drive on the tool or accessory, then insert fully until retention features engage. Reinstall any retaining clips, pins or fasteners according to the tool manufacturer’s instructions and verify secure coupling before applying torque. Perform a brief functional test at low speed to confirm correct engagement and absence of excessive play.

Usage recommendations

Always disconnect the power source and follow safety instructions from the power tool manufacturer before performing replacements. Inspect mating parts for wear or damage and replace related components if necessary to ensure reliable torque transfer. Use the joint piece only in compatible drive systems and avoid applying torque beyond the tool’s rated capacity.
