Buildex 12G x 20mm Class 4 metal cladding screws are short self-drilling fasteners with a TEKS point and sealing washer, supplied in a 100 pack for fixing metal cladding and fencing to light-gauge steel. The TEKS self-drilling tip cuts through metal and drills its own hole, removing the need for pre-drilling.

  • Gauge: 12G
  • Length: 20mm
  • Diameter: 5.5mm
  • Head type: Hex head
  • Point type: TEKS self-drilling
  • Finish: Class 4
  • Pack quantity: 100

The Class 4 finish provides a high level of corrosion protection, suiting severe external environments and structural applications exposed to weather or coastal conditions. The short 20mm length is ideal for fixing cladding sheets directly to thin steel, the hex head drives with a nut driver, and the seal helps keep the fixing weather-tight, making this 100 pack a reliable choice for cladding and fencing work.

Satisfied customer

Had been looking at the Buildex 12G 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.

Absolutely love it!

Had the Buildex 12G on my wishlist for a few weeks and finally pulled the trigger. Arrived in 2 days which was a nice surprise. Build quality is solid and exactly what the photos showed. My partner uses it every day now and has already asked me to grab another one as a gift.

Best buy of the year

Ordered Thursday and had it by Saturday. Packaging was really good — nothing moved around. Works exactly as expected and the price was well below what I saw in stores.
