How to use

Select the appropriate hex size that matches the fastener head and insert the short or long arm into the screw socket depending on the clearance and required leverage. Use the long arm for increased reach or higher torque and the short arm for tighter access and finer control. Apply steady, even pressure to avoid rounding the fastener; reposition your hand on the long arm when more torque is needed. After use, store the hex key in a tool holder or pouch to protect the working tip and maintain alignment.

Usage recommendations

Inspect the hex key and fastener for wear before applying force. Use the long arm for tasks requiring reach or additional leverage and the short arm when space is limited. Avoid applying excessive impact or using the hex key as a pry bar to preserve the tool’s shape and working edges.
