How to use

Select the appropriate bit tip and size for the fastener to ensure proper engagement.

After use, return bits to the organizer to keep the set complete and protect tips from damage.

Usage recommendations

Prefer impact-rated bits when using impact drivers to extend tool life and reduce bit breakage. Match the bit size precisely to the screw head, use the correct drive type, and maintain steady alignment between bit and fastener to minimize wear and prevent stripping.
