🔩 Chenango Supply Phillips Fasteners Miami-Dade Compliance Review

Works perfectly. Drill a pilot hole, blow out any remaining concrete/stone dust and they work great. Commonly used for attaching foam insulation to concrete garage walls etc.

As far as I can tell, just as good as faucet-cons. Although much cheaper. Caution - they were used to secure formwork in a cast concrete base. For short-term use, they were indistinguishable from faucet cons. Anyway, I don't know anything about the durability.

The screws themselves work great. I did a test on a replacement unit with a pry bar and they are holding up great. Loses a star for the "drill included" which gave me soft after about 15 holes. I picked up a DeWalt drill bit from one of the other comments and it hasn't shown any wear yet. I wish I could only take off half a star as the product is really about the screws and not the bit, but I'm hoping to save someone time by immediately recommending they buy a better drill bit!
