I usually get my t-nuts from McMaster-carr, they have stainless, but for some reason the don't have it in 8-32.....Also stainless seems very expensive. $5+ for 10.......What i do is buy the steel ones and lay them on a cardboard and paint them with Brownell's Alumina-Hyde-ll, its an epoxy paint, and it comes in flat and gloss black, i find it holds up very well...The down side is, it takes 2 weeks to set and dry, so you have to do a bunch at a time....Tom
