What Customers Are Saying

Customers overwhelmingly praise these lag screws for exceptional holding power and reliability in demanding wood projects, with nearly 9 in 10 expressing strong satisfaction. Reviewers consistently highlight superior grip, aggressive threads, and the Torx drive system that prevents stripping and enables smooth installation with impact drivers. Many report successfully securing heavy components like 4x4s, deck beams, and mounts supporting over 1,000 lbs without movement. While most users install without pre-drilling, some note that dense or treated wood benefits from pilot holes and proper technique. A few mention higher pricing compared to alternatives, though most consider the performance worth the investment.

Pilot hole needed.

Would Recommend

This round head lag screw has a large diameter head which is good for clamping but causes a problem. My driver extension has a non-rotating sleeve for guiding the screw and driver extension. The sleeve would not go over the large diameter head on this screw. This caused a lot of wobble and the screw was difficult to start into the wood. I would definitely drill a pilot hole the next time I use this screw. I just did the install so cannot comment on the corrosion resistance yet.
