Will false bottom support nuts damage the bottom of NO pot?

[kebabman]

I am still mulling over the best way to give a little bit of false bottom space under my perforated s/s sheet mash tun false bottom.
If I use 6mm long bolts through the 1mm thick false bottom sheet with a spring washer and a nut will that leave a bit of the bolt protruding through the nut as I am worried that the metal of the nordic optical pots seems thin and I don't want to make a load of indentations in it each time I brew.
Even if the bolt finishes flush with the nut (or I get it flush with extra washers etc) will that still cause damage?
Cheers

If you are worried use Dome nuts . . . I haven't found it to be an issue with my 24L Thermobox

I've not yet played with my 80L and the 50L is still in transit

I use half a dozen M3 bolts and I haven't had a problem.

You won't have any problems K. I use 12mm bolts, see here and haven't had any problems.
There's no issues regards scratches and no way the fb bolts will dent the base :thumb:

Not if you put the sharp edges of the mesh into a peice of pvc tubing
