My car was making a weird noise the other day. I took a look at the belt and it was worn so I picked up a new one. Well, I went to replace it today and found that the nut for the power steering pulley had backed off and was of course on the road somewhere. Is this a flanged nut? There is only about 11.1 mm of thread to work with on the shaft and all the nuts I find are 11 mm deep and they are not flanged. Flanged 14mm nuts are 14 mm deep. Anybody have a junk pump laying around with the nut they want to part with? I have checked Fastenal and Mcmaster Carr and not much luck. I assume it is a 1.5mm pitch thread.
