What Customers Are Saying

Customers overwhelmingly praise these structural screws for exceptional strength and reliable holding power in demanding applications. Reviewers consistently highlight the aggressive threads and large grip that bite deeply into wood without loosening, even in aged framing. Many commend the effortless installation with the T30 Torx bit, noting they drive smoothly without pre-drilling. Users describe the screws as high-quality, professional-grade hardware that outperforms other brands across diverse applications from deck work to structural repairs. A few mention the T30 bit size requires preparation, though most consider them excellent fasteners worth recommending.

Worked better than expected and a fence less than 4 years old that was operated from the post. The extract screw length helped realign.

Meh so worked well some didn’t

Would Not Recommend

Bought 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
