How to use

Store bits in the original case or an organized rack to maintain order and protect tips from damage.

Usage recommendations

Match bit profile and size precisely to fastener heads and avoid excessive torque that exceeds the bit or fastener capacity. Clean and dry bits after use and keep them in their case to reduce corrosion. Replace worn or damaged bits to maintain safe and accurate fastening.
