Stainless steel nuts & bolts in CEI thread cost a bloody fortune. For now I have found a local supplier where I can order setscrews in Whitworth thread, I cut this off and re tap in CEI. They even come with the heads stamped so I can mirror polish these my self.
Does anyone know of an organisation who can supply 1/4, 5/16, 3/8, 1/2 inch nut and bolt blanks in Whitworh spanner sizes in stainless steel please. Both A2 and A4 will be fine. Mind A2 is better cos it's cheaper.
