What size rivnuts and screws
I used aluminum rivnuts (10-24) and stainless 10-24 x 3/4” Philips head with a stainless washer and lock washer. Also bought a nice Astro 1442 rivnut set from amazon. I figured get a nice rivnut set because I’ll use it for other things I originally bought a cheap rivnut gun from harbor freight but it didn’t hold up to long
I’m thinking aluminum and aluminum too should dis similar metal reaction.. and there’s no real load to be concerned with ..
