Hi all,
The slingshot copper t-nuts are too chunky for my track system (left in photo). I sourced some thinner copper ones that are fine. BUT, just out of curiosity, I grabbed a relatively cheap bag of stainless steel t-nuts (right in photo).

Anyone tried/been using stainless t-nuts witouwi issue?

I use the copper ones but thought I'd ask....as my foil will sink like a stone if they are unreliable.....
