In a work project we need a nut size M13, that can resist corrosion in harsh weather and light electric current.
I also need that nut to be weldable with galvanised steel.
So far a Silicon bronze nut would do, I found a provided in inch size which was fine at first but now the client request for metric size fasteners.
So i either need a metric silicon-bronze cap nut provider or a different type of fasterner that has a sealed end, can be welded to steel and superb resistance to corrosion.
Thanks

RE: Special hardware
Since you are working with different metals (bronze, steel, zinc) you won't be able to weld them together. Maybe brazing or silver soldering. Of more concern to me is the galvanic corrosion issues with these metals. Steel and zinc are anodic relative to the bronze and would be subject to galvanic corrosion in the harsh weather conditions you mention. Is the electric current part of a system to reduce galvanic corrosion?

Regarding the nut itself, if you can't find one that suites your application, you can always machine one from bronze. Is there any reason you can't use some type of stainless steel? That would at least be closer on the galvanic chart. The zinc will still be an issue, however, but that's typically expected.

The nut would be tig brazed to galvanised steel. A welder told me it was possible.
The electric current is due to being near a big 100's MVA transformer, the static and magnetic friction.
I would rather not have to machine one but it might be the end solution. The inch one was expensive already...
