How to use

Select the bit matching the screw head profile and insert it into a compatible bit holder, ratchet or powered driver with a 1-inch (25.4 mm) shank accommodation. Ensure the bit seats fully in the screw head to avoid cam-out or tip damage. When using a powered driver, choose appropriate speed and torque settings for the screw and base material. Replace worn or damaged bits to maintain performance and safety.

Recommendations

Use the set for routine fastening where a compact selection of durable bits is required. Store bits dry and clean after use, and avoid excessive torque on worn tips to prolong service life. For high-torque or heavy industrial fastening, consider using full-size impact-rated bits designed for such applications.
