How to use

Select the bit that matches the screw head profile and size. Insert the bit into the 1/4" drive holder or the included adapter, then place the bit into the screw head ensuring a snug fit to avoid cam-out. For manual operation, use a compatible 1/4" bit holder or screwdriver handle; for powered fastening, secure the bit in the chuck or driver and apply steady controlled torque appropriate to the fastener and material.

Usage recommendations

Inspect bits for wear or deformation before use and replace damaged bits to prevent screw damage. Use the correct bit size and type for each screw to minimize rounding. When working with power drivers, start at low speed and increase torque gradually. Store bits in the provided case to maintain organization and protect the bits from corrosion.
