Optimaxx High Performance Woodscrew 4.0 x 50mm (Box 200)

These 4.0 x 50mm High-Performance Optimaxx Woodscrew have specifically positioned long thin grooves to dramatically reduce the pressure build-up on insertion by dispensing wood fibres, preventing splitting when screwing close to the edge. 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. Unique 24 grooves self countersink into all materials without the need to counterbore Sharp, wide, deep thread formation coated with a unique lubricant to facilitate fast continuous insertion Double reinforced collar strengthens the underside of the head The razor-sharp point with the thread starting at the very top gives you an immediate start even in the hardest, smoothest surfaces
