I found out its just easier to buy the boxes of bolts at ace as I am always using them for something else around the garage , one of my freinds found out why I don't loan out my engine stand bolts to anyone , as they assortment cost me about $50 ( I use the shouldered die bolts) they dont need washers as the heads and shanks fit into the tubes perfectly , also a company called MSC carrys USA grade 8's in bulk too for a decent price in chrome or black oxide .
