The ForgeFast Elite Performance MDF Chipboard Flooring Screw is specifically designed for fixing flooring grade boards to timber structures. The double cutting point breaks through the hard, dense surface of flooring grade materials. The anti-split, fast start thread can then engage quickly to form a rapid pick-up at the start of insertion. Reduced drive torque and no pre-drilling mean quick installations, whilst the fix remains firm with improved pull-out. The Under head ribs are designed for self-countersinking producing a flush secure finish on flooring. Double cutting point reduces splitting and drive time and is capable of penetrating 0.8mm steel. A firmer fix with reduced drive torque and improved pull-out provided by a serrated cutting thread. Improved holding power from the reinforced countersunk neck. Improved countersinking from the ribbed head. TORX compatible insert for a higher transmission of power. CE approved for use in load-bearing timber construction. Molecular lubrication. Elementech 400 surface coating provides corrosion resistance. Salt spray tested to 400 hours. A Non-Cr, Cr3+, yellow/zinc plated surface is environmentally friendly. Lasts up to 6 times longer than standard zinc screw protective coating. Suitable for interior use.
