Set of 5 new rear case screws and 5 accessory hold-down screws for your vintage IBM 51xx PC. If you restore vintage IBMs, you know these are usually one of the first things to disappear.
Should be an exact replacement for the rear case screws. Hold-down screws have a slightly larger head but are the same length and size.
These should be good replacement screws for:
-IBM PC 5150
-XT 516x
-AT 5170
-XT-286
-Aptiva 2168
