This special drive is a so-called hexalobular internal. Compared to less precise-fitting drive types like Phillips or cross recess, the contact surface is many times larger with our T-STAR plus, and the T-STAR bits are always positioned optimally in the screw head. The maximum, precise force transmission from the screwdriver to the screw that results from the use of T-STAR plus thus enables simple and ultra-fast work with much more efficiency than with other drives. What this means for you: No more annoying bit slips from the screw head – you can take care of serial fastening in no time at all!
Screw connections can also be true eye-catchers if required, with screw heads even presenting a key design element. Our universal screw with pan head is the best example of this! The practically spherical design of the screw head with T-STAR plus drive is particularly suitable for the visible attachment of metal fittings on wood. The flat underside of the head lies flush against the metal, making the pan head both a necessary and attractive part of the fitting. Meanwhile, the WIROX surface adapts to the colour of the high-quality metal fittings. What this means for you: No forfeiting the appearance of high-quality fittings through mismatched screw heads.
In contrast to the partial thread, the full thread on most of our full-thread screws covers the entire – or most of – the screw length from tip to head. The more thread turn a screw has, the greater the tensile and compressive forces that can be absorbed by these screws. We make particular use of this in structural wood construction, where our full-thread screws are called upon for heavy-duty wood connections. What this means for you: Wood connections with full-thread screws offer maximum reliability when it comes to resilience, and there's no need to use any ugly zinc-plated fittings!
While the tips of conventional screws are simply pointed, SPAX takes things to the next level yet again with the S point. The S point is characterised by serrations that stretch all the way to the front thread flanks. When you set the screw and start your cordless screwdriver, this thread immediately grips into the wood, effortlessly pulling the screw into the wood. This enables unbelievably rapid work without the risk of scratching the workpiece with slipping screw tips. What this means for you: No more slipping on hard and smooth surfaces – you save lots of time with serial fastening since no pre-drilling is required.
Effective corrosion protection is a must for screws used for outdoor structures not exposed to the elements. For this, SPAX has developed the WIROX coating, which far outdoes conventional galvanisation in terms of both protection and durability. Our WIROX-coated screws are significantly more resistant to mechanical stress than their counterparts with chromate conversion coating. 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. Our WIROX screws are the ideal choice for all open structures without direct exposure to the elements, such as carports and pergolas. For areas with extreme weather exposure, such as decking, we continue to recommend our stainless-steel screws. What this means for you: When you use our corrosion-protected screws outdoors, you can be safe in the knowledge that your structure is well fastened – in outdoor areas not directly exposed to the elements, WIROX keeps our screws statically rigid and reliably protected over many years. So there's no need for visual inspections every year!
