What Customers Are Saying

Customers overwhelmingly praise these lag screws for exceptional holding power and reliability in demanding wood projects. Most highlight the superior Torx drive design that resists stripping and grips securely with an impact driver, enabling smooth, fast installation. Reviewers consistently note the screws hold heavy structures—from banisters to gazebos—supporting weights over 200 lbs without movement, even withstanding 86 mph winds. The aggressive threads and large head create a firm, washer-free grip in dense and pressure-treated wood. Some mention that using the correct T27 or Torx-30 bit and an impact driver is essential for optimal performance. A few experienced head stripping with incorrect tools, but nearly all attribute this to improper technique rather than product defect. Overall, customers consider these screws worth the investment for their reliability and strength.

Excellent for use as a Tent Peg

 Would Recommend

This product is used by me most often as a tent peg or to hold down something in the ground. During this past winter while in Florida, we had a wind gust of 86 mph and a hanging plant stand did not fall over when being held down by three of these screws. Ofcourse, this is not what they are designed for, but they also work great for screwing large timbers together, after you have predrilled the holes for them.

GARAGE CONSTRUCTION REINFORCEMENT

 Would Recommend

This Lag Screw and the others work perfect for my project to re-support my Garage and replace sagging beams. I am now able to use Advanced Framing techniques to build most of the interior and supports. Definitely a value over purchasing Truss screws and components from other manufacturers.

Best Lag Bolt I Ever Used

 Would Recommend

A little expensive, but worth every penny. I used 4 of these to hang an articulating television wall mount. The TV (50 inch Hitachi plasma) weighs 117 pounds, and I really didn't want it to take a big crash. I had to go through 2 inches of wallboard and furring strips before I hit the studs, so the length of these was perfect as I wanted as much penetration into the studs without going all the way through. These things are the best thing since sliced bread...screwed into studs very easily with a...

Absolutely great lag screw...

 Would Recommend

This is one of the best lag screws on the market. Very easy to use, and will pull treated lumber up tight without just pulling through the wood. Also I haven't had one strip like lags sometimes do.

Worlds Toughest Lag Bolt

 Would Recommend

I used these lag bolts to bolt 2x4s to my garage wall to build wooden shelves. They powered through the studs with ease and the benefit of these having Torx heads mean that I was able to power these into the wall with ease. In the end, I was able to have over 1000lbs of load on my shelves with a few hundred pound of load to spare. The finish also ensures they will not rust. This lag is worth every penny.

quick driving lags

 Would Recommend

I have used these to attach wheels to several structures used in plays. They are inexpensive, quick to drive in with a drill, have a large diameter head with low profile and grip the wood very well. They are nice because the heads no not need a washer and do not interfere with the swiveling wheels. Wrongski
