SPAX T-STAR Wood Screws WIROX Csk Full 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. The ribs also help prevent thread stripping when fixing hinges etc. WIROX is an anti-corrosion coating, giving 10 times greater protection compared to yellow zinc plating. Fully threaded screws are particularly good for absorbing very high tensile and compressive forces in joints or for reinforcing wooden elements. 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 screws per charge). Recess: 4.0, 4.5 & 5.0mm = T20. Boxes of 200.
