🔩 Chenango Supply Miami Dade Compliant Concrete Fasteners and Screws Review

I used several of these to mount the heat pump circuit breakers to a standard concrete block. They work just as well as a well-known brand. I learned the hard way, DO NOT over tighten this type of hardened screw, it will snap leaving a plug in the hole that cannot be removed.

I used a hammer drill and the bit that came with it to drill through a concrete foundation wall. I drilled a hole slightly longer than the screw and vacuumed it before attaching the screw.
