Motherboard screws brass standoff hex spacer screw PC case male female
Motherboard screws are the threaded separator of defined length used to raise one assembly above another. They are usually round or hex (for wrench tightening), often made of aluminum, brass, or nylon, and come in male-female or female-female forms. In electronics, they are frequently used to raise a printed-circuit board above a surface. Insulating standoffs keep two parts from touching each other, thereby preventing electrical shorts. When used to fasten cable connectors (i.e. “D” connectors) together, they are called “jack screws”.
In contrast, a spacer is an unthreaded piece of tubing which lets the entire bolt pass through. Since they cannot be tightened, they are usually round. Ever Hardware provides motherboard screws with shoulder and customizable packaging.
Brass is a metal alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
By comparison, bronze is principally an alloy of copper and tin. However, bronze and brass may also include small proportions of a range of other elements including arsenic, phosphorus, aluminium, manganese, and silicon. The term is also applied to a variety of brasses, and the distinction is largely historical. Modern practice in museums and archaeology increasingly avoids both terms for historical objects in favour of the all-embracing “copper alloy”.
Brass is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, ammunition casings and valves; for plumbing and electrical applications; and extensively in brass musical instruments such as horns and bells where a combination of high workability (historically with hand tools) and durability is desired.
