This pack contains 200 SPAX Pozi Flat Countersunk Yellow Coated Screw, with a diameter of 4.5mm. 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.
Countersunk screws are screws that lie flat into the material that they are screwed into. They have flat screw heads that taper into the screw itself in order to make this possible. These screws are additionally coated in a yellow zinc coating, a very durable and waterproof coating. For the really important installations, SPAX will make sure the job is done right.
