Forgefix Forgefast Pozi Compatible Elite Performance Wood Screw Zy 4.0 X 70Mm Tub 600

The 4mm x 70mm Forgefast Pozi Elite Performance Wood Screw is supplied in packs of 600, designed for the most demanding structural applications requiring maximum penetration depth and exceptional holding power. This substantial length is ideal for heavy-duty framework construction, thick timber joining, post and beam installation, and applications where fixings must penetrate through multiple layers or particularly thick structural members. With a 4mm diameter and impressive 70mm length, these screws provide outstanding performance when joining materials up to 55-58mm thick, making them essential for substantial carpentry projects, timber frame construction, and heavy-duty structural installations. This size is particularly valued by professionals for fixing heavy joists, substantial posts, thick cladding over battens, and structural timber connections where maximum strength and reliability are paramount. Featuring the universally accepted Pozi compatible drive with 6 underhead lobes for clean countersinking, these screws deliver professional results in the most demanding applications. The reinforced countersunk necks provide maximum holding power under load. Despite the extended length, the anti-friction thread design effectively minimises timber splitting whilst preventing 'jacking' and spinning during installation. The serrated thread profile delivers superior pull-out resistance, and the double cutting point accelerates drilling through substantial materials and can pierce 0.8mm steel. The advanced Elementech 400 coating ensures exceptional corrosion protection for both interior and exterior structural applications.
