Optimaxx C288-805 4.0mm x 30mm Flat Countersunk Extreme Performance Woodscrews Self Cutting - Pozi Zinc Yellow - 1400 Pieces. Optimaxx is a top quality, high performance woodscrew that incorporates a number of unique features. A specifically positioned long thin groove dramatically reduces the pressure build up on insertion by dispensing wood fibres, preventing splitting when screwing close to the edge. 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. The double reinforced collar strengthens the underside of the head and allows for a wide deep pozi to be punched and the 24 unique slots help the screw self countersink into all materials without any surface damage.
