Post snapped in storm other night. It was originally concreted into a thick concrete retaining wall. I think my only option is use post anchors bolted into concrete.
got some Dial 6.8mm x 100mm coach screw and nylon plugs that require 10mm drill.
So drilled 10mm down to 100mm. Hammered plugs in. Upon screwing the screw 3/4 down it sheared.
So I have two issues... sheared screw deep in concrete and how to deal with these screws that say a 10mm drill which clearly are too tight and so shear.
For the sheared screw I think I’ll try drilling a new hole in the anchor I can’t see me getting that screw out.
but what do I do about shearing screws? Are Dial just low quality or are they not suitable for concrete? Shows brick on the packet. Drilling 12mm hole I assume is too wide then. But 10mm clearly is not big enough even though manufacturer says that. Don’t get it.
Thanks
