Buildex 12G x 50mm Class 4 roofing screws are timber roofing fasteners with a Type 17 point and a sealing washer, supplied in a 100 pack. The Type 17 point with a cutting flute gives fast, clean starts in timber and helps reduce splitting as the screw drives home.

  • Length: 50mm
  • Head type: Top lock hex head
  • Point type: Type 17

Brilliant Aussie deal

Been buying Buildex gear for years and this is one of their better ones. The Buildex 12G quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
