Yes I am curious. If the bolt still has its original finish I would consider it a stain. The pin itself in the hinge is what bleeds the rust on the fateners and hinge. The part of the pin inside the center section that pivots in particular. A stainless hinge pin is the real solution IMO. And a stainless sleeve in the hinge center section. Grease zerk would be nice as well.

FYI, I copied this whole thread over here as this is a more appropriate place and it will be easier for people to find it when looking.

I know you take your job seriously so make sure to lock the old thread.

Pendy,

I just completed a thorough metal exam on some new bolts and some old ones. On the new ones, I noticed the finish kinda sucks. It's just not clean or uniform.

As for the ones I have that have rust all over them, it is the bolts themselves that are rusting. The pins and hinges showed no sign of rust, at least not in a way where it would be on some heads and some threads like it is. Usually when the hinges bleed I am able to get the rust off quickly but you can tell this is the cause of the rust.

Well there it is then. I was suprised to see the head of the bolt showing rust in your picture. The coating put to your bolts indeed does suck. I have had better luck with some of those style bolts, but it is hard to "guess" the difference, if any from what you were working with. So maybe my "luck" is shortlived.

I do understand what JL was trying to point out though. Many other European vehicles I work on have a similar coating put to all the suspension bolts nowadays. And the coating holds up underneath vehicles where the greatest chance for rust is. Must just be a LR short straw in this application.

Yeah I agree. It's weird because not every bolt rusted the same way or in the same spot. I talked to a few others with these bolts and they had the same issues. Oh well. The stainless bolts with factory heads in the link I provided look nice and factory and don't have the same issue.

Perhaps there are different suppliers of the bolts involved? This could confuse the issue. It is very easy for a manufacturer to make a plating that will last forever, but for some reason this is becoming less common to see over the years.

Mine are genuine but that doesn't mean different anything since rover uses many suppliers

Trust me these bolts do rust! In Europe all the puma have these new bolts. They feel very light, almost like kind of aluminum. And i know guy's that bought a brand new 2011 puma and the bolts are rusting! not a lot but it looks cheap on a new car. Most of them are changing them to ss as well. I do like the puma hinges!
