How to use

Insert a compatible ISO 1173 style C 6.3 bit into the holder until it seats securely in the stainless steel sleeve. Fit the hex shank into the chuck or bit holder of a manual screwdriver or a powered driver with a 6.3 mm hex interface. Apply steady pressure and appropriate torque for the fastener being worked on. After use, remove the bit and store both components to avoid wear and corrosion.

Recommendations
