Very beefy! Installed usk g a Bosch Bulldog for the hole and impact to get it secured with a post bracket. Drill the hole deeper than the bolt or the concrete dust has no place to fall down when it bites itself in!

I use these to fasten deck ledgers to concrete and block walls, they work very well.I fasten them w/an ac powered Milwaukee impact gun avoiding the grind of a socket and rachet.

I used 1/2” x 6” tap cons to secure 4 x 4 pressure treated post to block wall. I needed the post for sail shades. I worked great

Used these for a fence project where I was able to use so existing concrete. Very strong and reliable, ran out and used some other anchors - they didn't feel as sturdy so I bought more and of these and delayed my project. Worth it in my opinion. They are expensive though....but again worth it for my use case in which I needed reliability. Takes a little more effort but again, more durability. Recommended.
