What Customers Are Saying
Customers overwhelmingly praise these fasteners for exceptional holding strength and effortless installation across diverse projects. Reviewers consistently report outstanding performance in decks, railings, cabinetry, and heavy-duty applications, noting the non-threaded shank design creates tight, rigid joints with no movement. Many highlight smooth driving through thick lumber with impact drivers or standard drills, and appreciate the included driver bit. Users report these outperform traditional bolts and lag screws. While some mention the price is steep, most consider the reliability and performance well worth the investment for future projects.

Great Fasteners
Would RecommendI used these to attach 4"x4" posts to a pallete while making a fire woodshed. They hold tight, drive easily and seem like they will be strong and stand up to the test of time.

these large screws make it easy to build large framing projects. They enable you to get into areas that you can't swing a hammer and they keep the joints tight.

These really work!
Would RecommendThese are a really great item to use while working on projects. They’re long enough, strong enough, and durable. My only complaint - it took a bit extra work to sink the heads, but it was worth it.

Fasten is the key word!
Would RecommendI was amazed at the pulling power of these fasteners. I used them to build a shop bench to hold my table saws. Very impressed when driving them through 2x4 and 2x6 how well they pulled the frame together for me. I did end up pre drilling the holes because some of my lumber was a little dried out. NOT ONE STRIP OUT SCREW HEAD. You will not be disappointed.
