Optimaxx C288-535 5.0mm x 70mm Flat Countersunk Extreme Performance Woodscrews Self Cutting-Pozi Zinc Yellow-200 Pieces, Yellow
Optimaxx is a top quality high-performance wood screw that incorporates a number of unque features.
A specifically positioned long thin groove dramatically reduces the pressure build up on insertion by dispencing wood fibres, preventing splitting when screwing close to the edge. Finally, a sharp saw-tooth formation cut out of the bottom threads bite into the timber reducing torque and resistance, enabling fast penetration without a pilot hole.
