ForgeFix ForgeFast Pozi Compatible Elite Performance Wood Screw ZY 4.5 x 50mm Box 200 FFP4550Y

ForgeFast Pozi-compatible wood screws, 4.5mm x 50mm, supplied in a box of 200. The diameter and length suit thick timber assemblies such as floor joists and structural framework, giving deep penetration and strong holding power for interior use.

The screws have a universally accepted Pozi drive with six underhead lobes for improved countersinking and reduced surface dust, plus reinforced countersunk necks for reliable fixing. An anti-friction, serrated thread reduces timber splitting, jacking and spinning while improving pull-out resistance and drawing strength, with lower insertion torque. A double cutting point speeds up drilling, reduces clogging and can pierce 0.8mm steel.

They're finished in Elementech 400, an anti-corrosive coating said to last up to six times longer than standard zinc, free from Cr6+ and salt spray tested to 400 hours.
