How to use

Insert the bit into a compatible 1/4" bit holder or directly into the screwdriver chuck if supported. Ensure the bit seats fully and locks in the holder before applying torque. Use appropriate screwdriver speed and torque settings for the fastener type and material to avoid cam-out or damage to the bit tip. Replace the bit when wear or deformation is visible to maintain fastening accuracy.

Usage recommendations

For best results, match the bit tip to the correct screw head profile and avoid excessive lateral force. When working in tight assemblies, the 37 mm length reduces protrusion and improves control. Store the bit in a dedicated holder or case to protect the tip from damage.
