7/8 7/16 1/2 Copper Male And Female Hex Head Standoff Yellow Golden coating standoff

7/8 7/16 1/2 Copper Male And Female Hex Head Standoff Yellow Golden coating standoff
 
Product Description:
What is a standoff? As the name suggests, the standoff is a screw with internal thread at one end and external thread at the other end, and the broad sense of the standoff also includes screws with internal threads at both ends. Its appearance is hexagonal, play a role in fastening and isolating, because it is generally made of hexagonal copper rods as raw materials, so the standoff is also known as copper column, hexagonal copper column, copper isolation column or copper gasket column.
The use of copper columns. Hexagonal screws are mainly used in computers, circuit boards and other industries, when one end is screwed into the locked object, the hexagonal column is exposed to the outside, which can fix or isolate other objects.
The main specifications of standoff are M3, M4, M5, M6, M8, M10, etc., and the specifications of the hexagonal column are 5, 6, 8, 10, 12, 15 mm, etc., of which the M3 series is the most. Materials in addition to copper and stainless steel, there are fast cutting steel.
 
Hexagonal studs are also known as yin and yang studs, it is one end of the internal thread and one end of the external thread, but are hexagonal, can play a role in fastening and isolation.
Mostly used in computers, circuit boards and other industries, when used, when one end is screwed into the workpiece being fastened, the hexagonal column is exposed on the surface, can be fixed or isolated from other workpieces. Such as in the computer mainframe, the external thread can be connected to the motherboard inside the mainframe, the internal thread can be isolated from the motherboard and sheet metal shell.
 
Applications:

Brass is an alloy composed of copper and zinc, brass composed of copper and zinc is called ordinary brass, if it is a variety of alloys composed of more than two elements is called special brass. Brass has strong wear resistance, brass is often used in the manufacture of valves, water pipes, air-conditioning inside and outside the machine connecting pipes and radiators.
Ordinary brass is a copper-zinc binary alloy, its zinc content varies widely, so its room temperature organisation is also very different. According to the Cu-Zn binary state diagram, the room temperature organisation of brass has three kinds: brass with zinc content below 35%, the microstructure at room temperature consists of a single-phase α solid solution, known as α brass; zinc content in the range of 36% to 46% brass, the microstructure at room temperature consists of (α + β) two-phase composition, known as (α + β) brass (two-phase brass); zinc content More than 46% to 50% of the brass, room temperature microstructure is composed of only β phase, known as β brass.
