Installation Notes

Insert bits should be seated fully and securely in the bit holder before applying torque to avoid cam-out or fastener damage. Select the correct hex size for the fastener to prevent stripping. Inspect bits for wear or deformation before each use and replace any bit showing visible damage. No special certifications or licensing are required to use hex insert bits, though always follow applicable safety practices when operating power tools.
