I have a 2.4mm rack rail, should I use Red or Purple?

If the rail thickness is >2.2mm, you'll definitely need the purple ones.

Anything to fit SKB racks??

From what I could find online, SKB racks don't use standard rack rails. They use rails directly pre-threaded for standard rack-mount bolts. As such, RackStuds will NOT work as they require the square hole. If you wanted the RackStuds for a specific reason, one option is to purchase the demo pack. Install the normal rack bolts you already have BUT from inside the case, fit your item over the bolts, then use the screw on covers from RackStud to secure the item. Personally, if you've invested in SKB racks, stick with standard bolts. I use mine in a network cabinet (no movement). 2x 1U rack mount switches & a 1U rack mount fan are the heaviest items. Everything else is patch panels or cable tidies.

I'm just installing a fixed shelf. Does it matter what colour colour/size I order?

YES Red = mounting rail upto 2.2mm thick Purple = mounting rail between 2.7mm and 3.2mm thick In other words, you need to know the thickness of your rack mounting holes. If you order Red and you have the thicker mounting rails, they won't lock in place. If you order Purple and you have the thinner mounting rails, they may screw tight to the item but they will remain loose in the square hole.

I want to use these to hold 2x 19" audio interfaces on vertical rails that dont have square holes.the m6nuts are too big.what size of these do i need

Sorry, but Rackstuds will only work with square punch vertical rails, much the same as cage nuts. Your options are limited if the holes are round and not threaded.
