ForgeFix ForgeFast Pozi Compatible Elite Performance Wood Screw ZY 4.0 x 50mm Tub 900 FFP450YT

ForgeFix ForgeFast Elite Performance wood screws, 4.0 x 50mm, supplied in packs of 900. This length suits heavy-duty applications such as thick timber joining, framework construction and decking or fencing structures, generally where materials up to around 35-38mm thick need to be fixed together.

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

They're finished with Elementech 400 coating, an environmentally friendly, Cr6+-free anti-corrosive finish tested to 400 hours' salt spray, suitable for interior and exterior use.
