Introducing Anti-Split Fast Drive Elite Performance Woodscrews. Features include Elementech 400 surface coating for corrosion resistance, salt spray testing for up to 400 hours, and an environmentally friendly Non-Cr, Cr3+, yellow/zinc plated surface. This screw's protective coating lasts up to 6 times longer than standard zinc screws. The double cutting point reduces splitting and drive time, while the screw is capable of penetrating 0.8mm steel. Its serrated cutting reduces torque for a faster, firmer fix, and provides improved pull-out with a serrated cutting thread. The reinforced countersunk neck provides holding power, and improved countersinking is achieved from 6 angled lobes. Anti-friction properties prevent jacking, rotation, and splitting, making it suitable for interior use.
