Simpson Strong-Tie 10 x 50mm collated decking screws give you serious corrosion resistance for timber decking thanks to a 316 stainless steel construction with a zinc coating. The bi-metal drill point lets the screw bite cleanly, while the ribbed flat head pulls down for a tidy countersunk finish. This is a 500 pack.

  • Finish: 316 Stainless Steel with Zinc Coating
  • Head type: Ribbed Flat Head
  • Point type: Bi Metal Drill Point

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.

Great value for money

Spent a while looking for the right Simpson Strong-Tie and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.
