What Customers Are Saying
Customers overwhelmingly praise these deck screws for strong holding power and clean aesthetics with composite decking, with low-profile heads sitting flush and blending seamlessly. Many report excellent results with proper technique and the correct bit, though a substantial portion encounter countersinking issues where heads remain exposed. Several note the reverse threads cause spinning or stripping, especially during removal, and emphasize pre-drilling resolves most problems. Despite installation challenges and occasional defects, most customers consider them reliable and cost-effective for composite deck projects.

Would RecommendAlways reliable
Difficult Install
Would Not RecommendI purchased Deckforce for my Trex deck as I had run out of Cortex brand fasteners and Lowe’s did not carry Cortex at local store. The Deckforce screws were very difficult to bite into Trex board with many going in at an angle. Once installed they performed well in holding the deck board secure to the joist.

don't buy these
Would Not Recommendthese screws sucked. they would not pull in completely even with pre-drilling! Spend a lil more and buy the ones with the bit in the box that pre drills with a counter sink but included. we even tried doing that with these screws and they still didn't pull the Trex fascia boards in tight.
Easy to use

Buy a Bit
Would RecommendI have used better screws. The screws weren't bad, but... get a better T20 bit. The included bit wore out quite quickly. The screws themselves were good and held well.
