How to use

Select the Proline hex key and align its tip with the hex recess of the screw or bolt. Insert the key fully into the socket to ensure proper engagement, then apply steady manual force to turn clockwise to tighten or counterclockwise to loosen. Use controlled movement to avoid rounding the fastener head; in constrained positions, adjust your grip and leverage to maintain alignment. After use, store the tool in a toolbox or on a rack to keep the tip clean and undamaged.

Usage recommendations

Use the correct size hex key for the fastener to prevent damage. Do not apply excessive force or use the tool as a lever extension or pry bar. For high-torque applications, consider using a larger tool or a dedicated driver designed for increased leverage and torque control.
