Product description

  • The Phillips Wafer head incorporates a washer and low profiled dome head. The washer like head spreads the load and can not be pulled into the profile and crease it - unlike traditional countersunk screws. This not only provides a neater appearance - it also stops water potentially pooling and causing corrosion.
  • Self-Tapping Thread - cuts a thread as it's driven in so reuse doesn't weaken hole
  • Self Drilling Point Tip - no pre-drilling or pilot hole required
  • Fire Classification - A1
  • Eliminates uPVC Creasing - the head prevents creasing the profile unlike countersunk screws
