How to use

Select the correct metric hex size for the fastener, insert the short or long arm into the screw head depending on access and leverage needs, and apply steady torque using the T-handle. Use the long arm for reach and the short arm for higher torque. Maintain a straight engagement between key and fastener to avoid rounding the fastener head.

Recommendations

Inspect the tool and fastener before use. Do not exceed recommended torque for the fastener; supplement with a torque wrench or calibrated tool if exact torque is required. Keep the tool clean and store in a dry place to preserve the nickel-plated finish.
