The Optimaxx C288-810 4.0x40mm Woodscrews (Box of 1200) is a flat countersunk extreme performance, yellow woodscrew.

• 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.
