Description & Specs

Buildex 8-18 x 20mm Climacoat metal Tek screws are self-drilling fasteners for metal fixing with high corrosion resistance, supplied in a 50 pack. The Tek point drills its own hole into steel, while the countersunk ribbed head pulls down for a recessed, tidy finish.

  • Gauge: 8-18
  • Length: 20mm
  • Head type: Countersunk ribbed
  • Point type: Tek
  • Material/finish: Climacoat 3
  • Thread: Coarse
  • Drive: Phillips
  • Pack quantity: 50

The Climacoat coating gives high corrosion resistance, making these screws a strong choice for external metal fixing and treated pine applications. The self-drilling Tek point speeds up installation by removing the need to pre-drill steel.

Outstanding value

Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.

Satisfied customer

Had been looking at the Buildex 8-18 for a couple of months. Buildex build quality is obvious as soon as you open the box — feels solid and well finished. Easy to set up and works exactly as described. Delivery to Perth in only 3 days which is impressive. Will be buying more from SuperSaver AU for sure.
