Spax T-Star Plus Wirox Wood Construction Screw 8x140mm (Pack Of 16)

The Spax T-Star Plus Wirox Wood Construction Screws are hexalobular drive srews, the T-Star Plus drive type is significantly more precise than drives like Philips or cross recess. The contact surface is many times larger and its intelligent design ensure the T-Star bit is alwasy positioned optimally within the screw head. This allows you to deliver maximum, precise force, resulting in simple and super-fast work with much greater efficiency than other drives.

The Wood Construction Screws are partially threaded, making them ideal for fastening together: wood boards, panels, floorboards, and even squared timbers on load-bearing components like stud framing or posts. While the thread makes its way through the load-bearing component, the thread-free shank of the partial thread screw should pull all the way through the top attachment. When the screw is inserted further, the screw head pulls the upper component onto the lower one. By inserting the screw, maximum contact pressure is therefore created between the two components.

Spax screws feature 4CUT points, meaning the tip of the screws are not rounded, but rather shaped like an arrow.These four edges displace the wood fibres upon insertion and thus create space for the core diameter of the screw. The otherwise inevitable expansion at the core of the wood is effectively reduced, minimising wood splitting around the edges. The required cordless screwdriver torque is also reduced, since the screw core no longer needs to “squeeze” into the wood.

WIROX-coated screws are significantly more resistant to mechanical stress than their counterparts with chromate conversion coating or galvanisation. No chromium(VI) is used for WIROX, which means that even after years in an area not directly exposed to the elements, the screws are not only just as resilient, but are entirely environmentally friendly, too. WIROX screws are the ideal choice for all open structures without direct exposure to the elements, keeping them statically rigid and reliably protected over many years.
