A HUGE word of caution for you.....trust me this is real life experience.
Stainless steel screws work really great if the insert you're going into is steel. DO NOT put stainless screws into stainless nuts. They will gall. Know what that means? In short, the screw will seize in the nut and you'll never, repeat, never get it out. Ask any machinist, he'll confirm this. BE CAREFUL!
