Phillips Hex Head Machine Screw Washer Stainless Crown Bolt Flange

The phillips hex head machine screw is 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. Ever Hardware provides the custom-made phillips hex head machine screw and customizable packaging.

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 UNC 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. Motherboards and other circuit boards often use a #6-32 UNC standoff. #4-40 UNC thumbscrews are often found on the ends of DVI, VGA, and older Serial and Parallel cables.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal’s internal structure. Passivation occurs only if the proportion of chromium is high enough and oxygen is present.
