Workshop application

Built for strength, speed, and precision, the 4mm SPAX WIROX Countersunk Screws are the ultimate fastening solution for timber construction and general joinery, especially where long-term durability and clean finishes are a must.

Key Features:

  • T-STAR plus Drive 

    Engineered with SPAX’s exclusive T-STAR plus head, these screws deliver maximum grip and torque transfer with minimal bit slippage. The result? Faster installation, smoother drive-in, and frustration-free fastening, even during repetitive or overhead work.

  • Countersunk MULTI Head

    Featuring a 90° conical design with SPAX’s patented milling pockets, this head ensures flush, clean finishes without pre-drilling. Perfect for visible applications where aesthetics matter.

  • Partial Thread for Maximum Clamping Force

    Designed for joining timber components like floorboards, cladding, or framing, the unthreaded shank ensures tight clamping between elements. The screw draws the top piece snugly to the base material, ideal for load-bearing joins.

  • 4CUT Point – No Pre-Drilling, No Splitting

    The four-edged tip cuts through fibres cleanly, reducing splitting near edges and eliminating the need for pilot holes. Save time and maintain material integrity in every application.

  • WIROX Coating – Long-Lasting Corrosion Resistance

    Optimised for outdoor use in covered areas (like pergolas, carports, or partially exposed timber structures), the WIROX coating outperforms standard galvanisation without using harmful chromium(VI). Strong, sustainable, and built to last.

Ideal For:

Framing, decking understructures, external timber cladding (non-weather-exposed), furniture construction, and engineered wood installations.
