Computer case screwsComputer case screws are the

hardware used to secure parts of a PC to the case.

Although there are numerous manufacturers of computer cases, they have generally used three thread sizes.

The Unified Thread Standard (UTS) originates from the United States while the ISO metric screw thread is standardized worldwide.

In turn, these thread standards define preferred size combinations that are based on generic units—some on the inch and others on the millimeter.
