How to use

Select the correct metric size hex key for the fastener. Insert the short or long arm into the screw head depending on required torque and reach; use the long arm for greater reach and the short arm for increased torque. Apply steady force, avoiding sudden impacts. After use, wipe clean and store in a tool rack or pouch to prevent corrosion and damage.
