I was hoping there wouldn't be much of an electrolytic reaction Locky The headlight housing retaining bolts are stainless and I haven't had a problem there, they came out alright. However, my mate who has a boat said that he has seen some problems with stainless bolts freezing into steel but this is obviously a marine environment. The main areas I was thinking of doing this were along the front guards, the indicator panels to nosecones and the front valance panel, all areas where I have seen the factory bolts rust and snap far too often, resulting in many tears :'(. Surely stainless in those areas would have to be better than zinc plated steel? Maybe a drop of oil on the bolt might prevent any reaction taking place?
Still thinking about this. Simon where do you get unbrakos from? The two areas where I was thinking of socket head cap screws were the grill and the nosecone to indicator panel as they look a bit neater than hex bolts. All other areas I would stick with hex bolts as you can get a lot more force on them(until they snap!)
Would titanium bolts have the same problem - there is an ebay seller offering these (primarily for bikes, although some of the bolts would suit Datsuns).
Obviously unless the compounds of both bolt and panel are identical, there is always going to be an extent of electrolysis, but I was hoping to prevent snapping any bolts in the future, and what about the tensile strength of stainless?
