How to use

Insert the 1/4" hex shank into a compatible bit holder or power driver and ensure it seats firmly. Align the Torx T40 tip with the fastener recess, apply steady axial pressure, and turn the driver at an appropriate speed and torque setting for the application. For powered use, start at low speed to ensure correct engagement before increasing speed. Remove debris from the fastener recess between operations to maintain secure contact.

Recommendations

Use the bit with drivers that provide torque control and avoid excessive torque to prevent damage to fastener heads. Inspect the tip regularly for wear and replace the bit when signs of rounding or deformation appear to maintain safe, accurate operation.
