    I don't suppose there is a full list of screws, nuts and bolts for a T2 Kombi ?

    Good question as some people call them a rusty bucket of bolts and any one owning one must have a screw loose:D

    Don't think there would be a complete list of only nuts and bolts for a kombi. In the parts listing you would find it would mention the nuts and bolts used.
    Not sure how well you can torque stainless steel, when it comes to mechanical areas of your suspension and other areas where torqueing is required. I wouldn't used them in those area's.

    A2-70 is 304 staino and is slightly weaker than an 8.8 high tensile steel bolt but susceptible to cracking/breaking

    Does that go down the same path with A4 316 stainless steel?

    I thought the replacement choices were either Stainless Steel OR High Tensile............... as you can’t have both. :rolleyes:

    Purchased a lot of stainless when we resto'd Schmett years ago.
    Only for tinware and non critical applications. Stayed with original bolts for serious applications.

    A4 is better of marine applications
    All staino bolts will cause minor electrolytic action (and be the cathode) with steel aluminium and cast iron if in a wet (water) environment

    NSW rail had big problems with electrolytic action causing the frames to rust with the first generation double deck interurban carriages. The only place that they rusted was where the stainless met carbon steel. They had to scrap them. I have no idea what type of stainless the bodies were made from.

    I used stainless nuts on an exhaust on my Beetle rally car. The first rally the nuts came loose. After that I used Glenlochs which solved the problem.

    Everything is not as simple as it seems in engineering.

    If I have to mix metals (stainless steel, carbon steel, aluminium) I use anti-seize lubricant and always use copper exhaust nuts.
    Saves trouble down the track.

    They were in service from 1968 to 2002
    Had More electrical problems than rust, were converted to non driving carriages, but rust did finally do them in

    The electrolysis problem surfaced in 1976. I was working with the engineers at the time.
