Down here where I live, we have a place, locally owned, that has just about any bolt made in stock in just about any size you need. They also have a lot of other industrial supplies, LPS, WS-40, Brake Clean, etc. too. It's run by several women about my age. They also have one side of the store devoted to a woman's taste. So while you are shopping for bolts the wife or girl friend can be drooling over the stuff they like.
It's called Gulf Bolt and Screw. They also have a sister company across the street that deals in bearings, don't recall the name on that business.Ok, what is the name of that one, We have a place here in SA that is Quality Fasteners they also do stuff on the web, I can walk in and purchase what I need in most instances.
