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.

Easy to use

Would Recommend

Used 3 of these to secure a 4x4 to another 4x4. Predrilled small holes, drenched them in wood glue, drilled them into place. Very secure now.

Too expensive

Would Not Recommend

After purchasing and bringing home, researched online $57 vs $8, I returned the product to Lowe’s for refund,. Lowe’s is charging way too much for this and should review their pricing! Product is superb and would purchase again, but not from Lowe’s.

These are Fantastic

Would Recommend

I chose these to use to attach my deck posts instead of standard galvanized or stainless lags. When you factor the cost of a standard lag and a washer (washer not always necessary) these are about the same price. When you factor in that you dont have to pre drill holes these are a clearly superior product. The only issue I had was figuring out the correct star bit to use. You have to use a T27 star bit or they wont go all the way in. I will never buy another galvanized or stainless lag bolt...
