- 200x SPAX Flat Flange Head Screw for back-wall fastening 3.5 x 40mm T-STAR Plus T20

Product description:

The flat flange head screw range from SPAX for back-wall fastening is ideal screwing on fibreboards (MDH/HDF). These screws enable easy tightening and loosening of surfaces without damaging them, making removals easier. However, they remain firmly in place in the back panel and are greatly resistant to pulling out compared to conventional nails. They feature a self-tapping CUT tip and a wave profile on the screw tip allowing precise screwing without pre-drilling and ensuring a reduced splitting effect as well as a significantly reduced screw-in torque. Their large, flat, lens-free head ensure good stability and increase clamping pressure when screwing. This set of flat flange head screws is also equipped with a special drive T-STAR plus, guaranteeing precise fastening of the bit and better guidance, particularly when working overhead. WIROX stands for high-quality coated screws with a great degree of corrosion protection in the SPAX ecosystem, which are significantly more environmentally friendly contrary to conventional coating compositions.
