great service

The only negative was the barrage of emails about changes to the delivery and a duplicate of my order somehow remaining in the shopping cart.

As with most Simpson products, this is excellent quality hardware . However, you really need to be sure to get all the concrete drilling fines out of the hole before installation of the screw. If you experience an increasingly higher tourqe value (> 80 ft lbs) before full engagement you probably will need to remove fastener and clean out more residual fines.

Very helpful customer service. Product shipped quickly, and great quality.

Easy to install. I prefer these over expansion anchors because they don’t put expansive stress on the slab. And, I can add them to the slab in the places where the j bolts interfere with the framing. Note that I typically have to drill the holes past the 1/2” recommended over drill depth even after blowing out the hole. Apparently, the act of installing the screw creates enough concrete dust to fill the extra 1/2”.
And, Fasteners Plus gets them to faster than any other vendor. Couldn’t be happier.
