In boating, all stainless steel fittings that may come in contact with aluminium alloys must be insulated from them - if you look at any fittings designed for fastening to masts, for example, they will come with nylon insulation washers and gaskets.

The situation is not much worse than for mild steel in theory, but is worse in practice, because mild steel is usually fairly well isolated electrically by paint, where stainless is not.

In the case of door hinges, fastened with stainless bolts, the hinge should be insulated from the door skin by an insulating gasket, and the bolts through the door should have an insulating tube in way of the door skin. Not that much worry about the door pillar, as this is mild steel, although a similar insulating gasket would reduce the likliehood of corrosion.

further to this they don't want to deal with anyone in the west, as the bloke at rovercraft has stitched it up apparently and if you want parts from them you have to go through him over here with his juicy mark up....sad as they are bringing out recessed defender interior door panels

And apart from the fact that colin has gone bust so they are not bringing out anything

Thanks for the replies fellas

I sent Scorpion an email, apparently they dont make them anymore. Not sure how keen I am on the idea of alloy hinges. So I might just end up getting a set of bog standard ones

But Ill keep an eye out

Those stainless bolts look the bees knees. I saw that corrosion was mentioned further up. What if you were to smother them in Duralec? Its an anti corrosion thing for use between two different metals; designed for use on boats.

Just having a look at the Stainless bolt kits on the Stig's website

Stig's Stainless Fasteners

It says to suit Defenders 1998 on, did they change the threads or do they just have there info mixed up?

Also am I better off getting Hex head or TORX?

Thanks

do the standard ones wear out.......i have had my rig for four years and they are still good, who know when they were last fitted/changed

what's the price differance between standard and stainless?

The main problem is they rust and end up looking sh*t
