ForgeFix ForgeFast Pozi Compatible Elite Performance Wood Screw ZY 4.0 x 70mm Tub 600 FFP470YT

ForgeFix ForgeFast wood screws in 4.0 x 70mm, supplied in a tub of 600. This length suits heavy-duty structural work such as thick joists, posts, beams and multi-layer fixings where deep penetration and strong holding power are needed.

The screws have a Pozi compatible drive with 6 underhead lobes for clean countersinking and less surface dust, plus reinforced countersunk necks for extra holding power. An anti-friction thread reduces timber splitting and prevents jacking or spinning, while the serrated thread improves pull-out resistance and lowers insertion torque. A double cutting point speeds up drilling and can pierce 0.8mm steel.

An Elementech 400 coating gives anti-corrosive protection, said to last up to six times longer than standard zinc coatings, is free of Cr6+, and has been salt spray tested to 400 hours. Suitable for interior and exterior use.
