The Pozi Flat Countersunk Wirox Screws by Spax is an excellent high-quality screw coated with Spax's Wirox formula. It was invented by GKN Screws and Fasteners and continues to be the go-to choice for many in the construction industry. This is due to its deep eight-pointed star design that securely fastens into place, tolerating higher torque levels than the conventional Phillips head.
Other features that push the Pozi ahead of other screws heads is its ability not to cam out as easily. A lot of screws, after years of application, find themselves slowly slipping out; this is a problem the Pozi overcome. Alongside its effectiveness in securely burrowing a surface, its Wirox coating is a durable, waterproof, environmentally friendly coating, making this product perfect for open structures.
At ERoofing, we are proud to stock a wide selection of SPAX screw products. The world-famous Pozidriv or Pozi screw design uses a deep eight-pointed star design to secure the drill bit in place for a high level of torque. This tried and tested design has seen heavy use since its invention in 1962.
