Optimaxx is a top quality high-performance wood screw 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. 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.
Double reinforced collar strengthens the underside of the head, wide, deep Pozi recess dramatically reduces cam-out, unique 24 groove design self-countersinks into all materials without the need to counter bore. Sharp, wide, deep thread formation with a unique lubricant coating facilitates fast continuous insertion.
