What Customers Are Saying
Customers overwhelmingly praise these screws for their superior Torx drive design, which eliminates bit slippage, reduces driver fatigue, and prevents stripping compared to Phillips heads. Reviewers consistently highlight exceptional performance in outdoor applications, pressure-treated lumber, and decks, with many reporting durability lasting years without rust or failure. The corrosion-resistant coating and sturdy construction earn widespread trust for framing and general construction projects. A few mention minor concerns about the included driver bit's length or rare instances of snapping under extreme stress, but these are isolated. Overall, customers consider them a reliable, professional-grade choice.

Would Not RecommendThought these screws were better quality than they are. The threads aren’t normal & most of them failed to screw down completely, let alone countersink, leaving the screw heads about 1/8” above the surface of the wood before they just spin. The picture on the website doesn’t accurately depict the screw threads either. I will be returning them.

This screw works great. Newer style isn’t any good in my opinion. Had to search for this style.

Grip-Rite Primeguard 3-in Polymer Deck Screw
Would RecommendGrip-Rite Primeguard Plus #9 x 3-in Polymer Deck Screws (5-lbs) box gripped tight and drew down well into substrate. Star head DeWalt bit used in conjunction with screw allowed for quick and easy install. Bit release from screw was minimal to aide in quick and accurate install of planking material.
