Anyone got an ARB roofrack???

I'm in the process of 'reconditioning' our ARB roof rack. The rack (basket??) had been mounted to the legs with black HT bolts, and these are all rusty.
For those with an ARB rack, what bolts have been used..S/Steel?? Cad plated??
S/Steel Allen bolts have been used for the gutter attachments.
My inquiry is for the bolts thru the plates on the rack to the horizontal face of the legs.

I have 3/4 ARB rack on 100TD. Does not have gutter mount.
All bolts are SS allens.
Don't know if they came with the rack or not as I had it installed by local ARB dealer cos I'm slack and can (or could at the time) afford it.
Regards

Ever wonder what the speed of lightning would be if it didn't zigzag?

I'd use stainless bolts with a bot of antisieze to prevent galling

I wouldnt have thought galling was a problem, if you didnt do the bolts up too tight.

You'd be correct Bonz but it pays to be a bit ahead of yourself. Disimilar metals can do funny things sometimes

Galling is the process whereby two metals are brought together at high pressures (like doing a thread up really tight) and the two surfaces, in this case the bolt and the nutor threaded surface "weld" together, sort of like a cold weld. Vibration can then break these tiny weld further increasing friction between the surfaces and making them VERY difficult to persuade to part company.
