A Really Good Fastener
These fasteners worked great. Secured a PT floor plate to a concrete floor. Pre-drilled through the plate and into the concrete floor with a hammer drill and a 5/16 inch masonry bit. You will need an impact driver with a 9/16 inch socket to install the anchor. Make sure you drill the hole longer than the screw...or you will be screwed.These are top quality fasteners and actually arrived early. Thanks!

Easy to use
These bolts seem to be very good for bolting things to concrete. With the proper size hole, they seem to thread in and hold firmly. I drove them with an impact driver. Might be difficult with a regular drill or a wrench. I used them to bolt the posts of a gazebo to the concrete footings.

works great
put a 1000 ft/lb impact on them pulls the board to the concrete great. No breakage. Takes the worp right out of the treated lumber.

Great product.
Great product wrong size though. It was too long, 5”, instead of 4”. I’ll use it for wrought iron fence.

Excellent concrete bolt.
Great product. I used it in the stone walls in my basement. Holes were hard to drill, but these bolts went in great and are exactly what I needed.
