Computer case screws are the hardware used to secure parts of a computer case 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.
The 6-32 screws are often found on hard disk drives and the case's body to secure the covers. The M3 threaded holes are often found on optical disc drives and floppy drives. On older Serial, Parallel and VGA and DVI cables, 4-40 thumb screws are often found on the ends.
More modern cases from certain manufacturers (Dell, Gateway) and enthusiast cases will lack screws altogether, instead utilizing a tool-less design.

Famous quotes containing the words computer, case and/or screws:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
“Oh, that I knew where I might find him, that I might come even to his dwelling! I would lay my case before him, and fill my mouth with arguments. I would learn what he would answer me, and understand what he would say to me. Would he contend with me in the greatness of his power? No; but he would give heed to me. There an upright person could reason with him, and I should be acquitted forever by my judge.”
—Bible: Hebrew, Job 23:3-7.
Job, of God.
“Each of us is full of too many wheels, screws and valves to permit us to judge one another on a first impression or by two or three external signs.”
—Anton Pavlovich Chekhov (1860–1904)
