[Elecraft] OT Good Source for Stainless Fasteners and

[Gary Peterson]

Stainless hardware is commonly used on FM broadcast antennas.  Stainless is a bit on the gummy side.  When tightened, the threads tend to distort and this can make future disassembly a challenge.  Tower crews frequently end up twisting off nuts or bolt heads when replacing damaged elements.  If you are going to use stainless hardware, I suggest applying anti-seize lubricant, available at auto supply stores, to reduce seizing and galling.  I also suggest never reusing stainless hardware.  Replace with new.

“When using stainless hardware there is very little strength compared to a steel fastener.   

So the minimum strength needs to be confirmed.      You don't want the bolts to shear and topple over.    

Please be careful to get the right grade bolts.  You will not get what you need at a hardware store or a tractor supply.
