What Customers Are Saying

Customers praise these deck screws for strong holding power and clean aesthetics, with low-profile heads that sit flush and match composite materials like Trex. Many report excellent results using quality T20 bits and recommend pre-drilling for optimal performance. The star head design drives smoothly when paired with proper tools. However, some experience persistent countersinking difficulties, with heads remaining exposed or spinning without fully driving. A few note reverse threads can strip holes or damage composite if removed. Despite these drawbacks, most customers find them reliable for professional-looking deck installations.

Good screws for composite decking

Would Recommend

We bought these to go with composite decking. I expect them to far outlast the nails use in the previous deck floor.

Buy addition T20 drill bits if you buy these!

Started decking with those and switched to screws with bigger head as question whether they will really hold
