SPAX Countersunk, Full Thread, Timber Construction Screws, Wirox Coated

The SPAX Timber Construction Screws range is a heavy-duty selection of structural fasteners engineered specifically for high-load timber-to-timber connections. Featuring advanced thread geometries and optimised head designs, these professional-grade screws provide enormous pulling force and significantly higher load-bearing capacities than conventional wood fixings. Ideal for roof truss construction, oak timber framing, joist tracking, purlin connections, and structural insulation layouts, this high-performance collection delivers an unyielding mechanical connection interface built to streamline major carpentry projects safely.

Ultimate Pull-Through Force

Features engineered large washer and countersunk head configurations that maximise clamping pressure between timber members, successfully preventing pull-through failures across heavy structural framing layouts.

No-Pre-Drill Efficiency

Engineered with a patented 4CUT point that effectively displaces wood fibres as it drives, eliminating the need for pre-drilling to significantly lower contractor assembly and on-site handling tracking times.
