[TheForge] Setting screws in concrete floor Mostly OT

[Ron]

I use "drop-in" anchors quite often to mount heavy items to concrete walls, 
floors and ceilings. you drill a hole to the depth of the anchor use a punch 
to set it then bolt down whatever you want. Here is a link to some 
"drop-ins" http://www.confast.com/products/drop-in-anchor.aspx
Hope this helps
Ron
