What Customers Are Saying
Customers overwhelmingly praise these screws for exceptional strength and durability, with aggressive threading that bites deeply into wood and holds securely without pilot holes. Most highlight effortless installation, especially into aged lumber, and credit the T30 Torx head for reducing stripping and enabling better torque transfer with impact drivers. Reviewers consistently report superior performance across demanding applications—from deck framing to structural reinforcement—with many noting they outperform traditional fasteners. A few mention higher pricing and occasional defects, but these concerns are vastly outweighed by widespread confidence in reliability and holding power.

Meh so worked well some didn’t
Would Not RecommendBought these and it was a 50/ 50 if they was going to strip half way through my boards, wasn’t nothing crazy just a true 2x6 going into a pole. Ones that worked went well but those that didn’t stripped the head only half way and couldn’t retrieve them had to cut em off plush
