Review on Zinc Plated CONFAST Wedge 🔩 Anchor Fasteners for Strong and Reliable Connections by Steve Campbell

Cheaper than Red Head at Home Depot (Arizona). Concrete slab and footer. They clip into a 1/2" hole like they should. I like that the first 1/4 inch or so is unthreaded so the threads don't get messed up when you punch the crap out of them, um putting them in. I screwed the nut right underneath flush with the top and then pushed it in. Worked great and kept the threads intact.I will keep an eye out for this brand from now on.
