|Yea thatís called a machine bolt, AKA the most popular bolt in the world, AKA the bolt type that can be found at any hardware store in the world. I would use 3/8" stainless steel bolts if itís outside or 3/8" grade eight bolts if inside. If you place stainless steel hangers you MUST place stainless steel bolts. DO NOT mix grade 8, 5, or 2 bolts with stainless steel hangers.
The main problem is that I need a a bolt that will take a nut at the back, rather than a concrete expansion bolt.
Are you bolting the wall for lead climbing? What are the bolts going to be used for?
