SPAX T-STAR Wood Screws WIROX Csk Partial Thread

A SPAX screws are a combination of unique features making them, without doubt, one of the best wood screws available. The 4CUT point bores into wood, dividing the fibres and minimising the chance of splitting. There is no longer a need to drill a pilot hole in most woods. The deep thread with patented serrations pulls the screw into the wood, significantly reducing the driving torque required (more screws per charge). The patented MULTIhead has self-countersinking and stopping qualities at the same time. Ribs on its underside cut into the wooden surface, so the head sits flush with the surface. WIROX is an anti-corrosion coating, giving 10 times greater protection compared to yellow zinc plating. Partially threaded screws are particularly suitable for fixing wooden boards to wooden beams, for example. As the thread tightens securely into the lower piece of wood, the upper piece of wood is forced tightly against the lower piece by the screw head. A Torx head has two major advantages. Hardly any pressure is required to keep the screwdriver tip in the head recess, virtually eliminating the chances of cam-out. The transmission of the driving force is radial rather than axial, so less effort is needed (even more screw per charge). Recess: 3.5mm = T15; 4.0, 4.5 & 5.0mm = T20; 6.0mm = T30 Boxes of 100.-bg
