Wrong drill bit size listed on label.
I bent 3 screws before I realized that the holes were too small. 1/4" is not the correct size drill bit. Wasted my time & gas.

More solid mounting in cement than competitors.
As a contractor, I try to buy these instead of tapcon's! Solid mounting and not as brittle!
