What Customers Are Saying

Customers overwhelmingly praise these screws as the go-to choice for fastening into concrete, brick, and masonry. The star-shaped driver bit is frequently highlighted for eliminating bit slippage and enabling smooth installation with impact drills. Many appreciate that kits include both masonry drill bits and star driver bits, making the job convenient and complete. Reviewers consistently describe exceptional holding power and reliability across applications like securing wood, pegboards, and door frames. A small number report occasional screw breakage under high torque or improper drilling, though most consider these screws the best available option for masonry work.

Securely secured secure subfloor to basement slab

Would Recommend

We purchased these to attached a OSB subfloor to a basement slab through a vapor barrier. Overall, installation was pretty simple, but on every 20th screw or so, the hole would strip out and the screw would spin freely, not securing the subfloor. We're not sure if this is a defect in the concrete used to pour the slab, or the screw, but it is frustrating. Overall, a good product and worth the price.

These are great for attaching wood to masonry. You definitely need the recommended bit and a hammer drill.

Quality products, at decent prices.

Would Recommend

They work as intended, it would be nice to have an assortment of head sizes, as they are all large, but the range of lengths is nice to choose suitable. They are as intended.

The "Kleenex" of concrete anchors

Would Recommend

They do what they are intended to do. I can't tell you another brand name of concrete anchors, so I suppose that should tell us something.

Anchored door frame into block wall

Would Recommend

I used these masonry screws to successfully anchor a loose basement door frame. All of the other solutions that had been tried had failed. I'm grateful for finding these anchors and concrete drill bits at my local store.
