ForgeFix ForgeFast Pozi Compatible Elite Performance Wood Screw ZY 4.0 x 40mm Tub 1200 FFP440YT

ForgeFix ForgeFast wood screws, 4.0 x 40mm, supplied in a tub of 1200. Suitable for deeper penetration applications such as structural joinery, decking subframes, fence posts and general construction where a longer fixing is needed for thicker timber.

The screws feature a Pozi compatible drive with 6 underhead lobes for clean countersinking and reduced dust, plus reinforced countersunk necks for improved holding power. An anti-friction thread reduces splitting and prevents jacking or spinning of joined timber, 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.

Finished with Elementech 400 coating, an anti-corrosive, Cr6+-free finish salt spray tested to 400 hours, suitable for both interior and exterior use.
