Does anyone know a supplier of screws with captive spring washers? I'm looking for M2, M3 and M4 machine screws of various lengths. I've tried TR Fastenings (you'd think if anyone would sell them it would be them... :? ) No luck there though. If anyone has used these in the past, do you have any advice? Any idea what the cost is like? I think I heard once these kind of fixings were expensive. I always thought that the cost saving from not having to fiddle around with individual washers on the production line would be huge, but maybe I'm wrong... Any suggestions gratefully appreciated!
