How to use

Insert the 1/4" hex shank into a compatible bit holder, quick-change chuck or screwdriver handle. Ensure the bit seats fully to avoid wobble and to maximize engagement with the Torx fastener. Apply steady, controlled torque while keeping the driver axis aligned with the fastener to minimize wear on the tip. For power tools, set an appropriate torque or use a clutch to prevent over-tightening.

Usage recommendations

Use the bit with matching T20 Torx fasteners only. Inspect the bit for wear or damage before use and replace if the tip shows rounding or deformation. Store the bit in its blister or in a designated bit organizer to protect the tip and maintain compatibility with 1/4" holders.
