I have used these on a bolt climb and as main rappelling anchors, 3/8 x 3 1/2", but now I only use fixe double wedge stainless steel. You can buy them cheaper from Fixe than anywhere else, google it. the bolts are about $6 each, you can buy their hanger plates too. Lots of tag pits have home made hangar plates made from angle iron with holes drilled in it. Very beefy.
Keep in mind the low strength of the bolts from home depo and lowes. I knew what I was getting into when I bought them and used them. most of the bolts I have installed have been strippedof their hangers from the bolt climb so its a moot point now. Ive bought a lot of hanger plates from on rope AT tag and at the MVOR's. saves on shipping.

I don't care what you think about your "little Ohio caves", if you place a non-stainless bolt, then when someone returns to that cave again (in 5 years) they're going to re-bolt it when they find a mystery rusted bolt. Find someone with experience to show you how to set them, your life is literally on the line, and any stranger who finds your bolts later will expect a trustworthy bolt.
