One 3' long 4x4 post for a deck railing needed to be anchored into an existing concrete slab. I bought a metal anchoring plate that had 4 screw holes that needed to be screwed into the concrete, and the 4x4 would sit in it and be held in place by 8 deck screws--4 on each side of the plate.
I drilled 4" holes using a 3/16" masonry bit and used 3" long 1/4" tapcons with hex head. Unfortunately, when I went to screw these tapcons in, they broke in half around 3/4 of the way in. I ended up having to ream out the holes a bit for them to screw into, but they weren't anchored as firmly as they would have been if they had been screwed into the original holes.
Should I have just pounded in lead anchors and saved the tapcons for brick and block?
