Gehmann Screws for 431 Sling (set male/female)
It's not a bad idea to have a couple of these in your rifle club's parts kit. We all lose parts like this at one time or another. How many of us have swept the floor after a practice session or a match and found all kinds of things other than brass? Buttplate rubber pieces, allen wrenches, screws, apertures, and all kinds of small parts. There's a good chance you've swept up someone's sling screw too.
