Installing expanson anchor bolts
Can I simply place expansion anchor bolt into the concrete before it sets?
Do I have to drill on the concrete after it is set?
Or is it best to insert slightly small diameter rod, say 7/16, and just drill slightly to 1/2 inch for 1/2 inch anchor bolts.
I am talking about the type of anchor bolt that expands as you tighten. It is first pounded into the concrete, but as one tightens the bolt expands in diameter.
Also, are this type of anchor blots good for pressure treated lumber sill?
