• Kreg's most common screw head type is the Maxi-Loc™ which is a washer head screw
• The large bearing surface of the washer head is designed to seat securely in the bottom of the pocket, providing a tremendous amount of consistent clamping force on the joint line
• Coarse thread with a larger diameter that provides greater holding power when driving a screw into soft material such as plywood, particle board, MDF, melamine and pine
