Review on 🔴 3840 Diameter Tapcon Redhead LDT by Gary Stringfield

I used these to screw on a pallet rack at work. I should have bought an inch shorter. They work, but this size is too big for the Tapcon technique. You need a very long drill bit to do deep rough work when applied horizontally to clear space and dust. I ended up with a few that I couldn't quite get through. If you go horizontal, you might not have to fight as hard with the dust left in the hole.
