SPAX Pozi Wood Screws YELLOX Csk Full Thread

SPAX screws are a combination of 4CUT point, MULTIhead and patented thread serrations 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. The YELLOX coating is 6 times more resistant to corrosion than the conventional bright or yellow zinc coatings used for screws. It is a more environmentally friendly and chromium(VI) free finish. Fully threaded screws are particularly good for absorbing very high tensile and compressive forces in joints or for reinforcing wooden elements.
