FAQ:

Q: What is a PC screw?

A: 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.

Q: Which Screws do I use for the motherboard?

A: Motherboards and other circuit boards often use a #6-32 UNC standoff. #4-40 UNC thumb screws are often found on the ends of DVI, VGA, serial and parallel connectors. More modern cases from certain manufacturers ( Dell, Gateway) and enthusiast cases will lack screws altogether, instead utilizing a tool-less design.

Q: Which screws to use to screw in motherboard?

A: Usually, the standoff has a #6-32 UNC male thread on one end which screws into a threaded hole in the case or motherboard backplate and a #6-32 UNC female thread in the other end which accepts a screw to retain the motherboard. Less often, the standoff has a female thread in both ends and a second screw is used to attach it to the case.
