How to use

Select the hex key that corresponds to the hex fastener size, insert the short or long arm into the screw head depending on required leverage and access, and apply steady torque to tighten or loosen the fastener. Use the long arm for greater reach and the short arm for higher torque. Keep the tool perpendicular to the fastener to reduce risk of rounding. Store keys in their compact holder after use to keep sizes organized and prevent loss.

Recommendations

For best results, match the hex key to the fastener head precisely and avoid excessive force beyond the fastener’s torque rating. Periodically inspect keys for wear or deformation and replace any damaged keys to maintain safe and reliable screwdriving performance.
