Forgefix Forgefast Pozi Compatible Elite Performance Wood Screw Zy 4.0 X 50Mm Tub 900

The 4mm x 50mm Forgefast Pozi Elite Performance Wood Screw is supplied in packs of 900, designed for demanding applications requiring extended fixing depth and maximum holding power. This length is ideal for heavy-duty structural work, thick timber joining, framework construction, and applications where the fastening must penetrate through multiple layers or particularly thick materials. The 4mm diameter with 50mm length provides excellent performance when joining materials up to 35-38mm thick, making it perfect for substantial carpentry projects, post and beam construction, and heavy-duty exterior installations. This size is particularly valued for decking support structures, substantial fencing projects, and timber framing where reliability and strength are paramount. Engineered with the universally accepted Pozi compatible drive and 6 underhead lobes, these screws offer clean countersinking and reduced surface dust. The reinforced countersunk necks provide enhanced holding power in demanding applications. The anti-friction thread design minimises timber splitting even in longer screws, whilst preventing 'jacking' and spinning during installation. The serrated thread profile delivers superior pull-out resistance, and the double cutting point allows faster drilling through thicker materials and can pierce 0.8mm steel. Protected by the advanced Elementech 400 coating with 400-hour salt spray testing, these screws excel in both interior and exterior environments.
