Computer 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.
