3/8 7/16 1/2 Carbon Steel Male And Female Hex Head Standoff blue Black Oxide Zinc 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:

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218 per cent to 2.11 per cent. It is also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Generally the higher the carbon content of carbon steel, the greater the hardness and strength, but the lower the plasticity. Commonly used steel grades and applications:
T7, T8: the production of bear a certain impact and require toughness of the parts. Such as sledgehammers, punches, chisels, woodworking tools, scissors.
T9, T10, T11: the manufacture of smaller impact requires high hardness and high wear resistance of the tool. Such as taps, small drills, punching dies, hand saw blades.
T12, T13: making tools that are not subject to impact. Such as files, scrapers, razors, gauges.
