M3 M2.5 Blue Yellow Galvanized Male And Female Hex Head Standoff Carbon Steel hexagon studs

A standoff is a specialized fastener with internal thread at one end and external thread at the other end. The broad definition also includes screws with internal threads at both ends. These hexagonal fasteners serve dual purposes of fastening and isolation.

Commonly manufactured from hexagonal copper rods, standoffs are also referred to as copper columns, hexagonal copper columns, copper isolation columns, or copper gasket columns.

Hexagonal standoffs are extensively used in computer assembly and circuit board industries. When installed, one end screws into the locked object while the hexagonal column remains exposed, enabling secure fixation or isolation of other components.

In computer systems, the external thread connects to the motherboard while the internal thread isolates the motherboard from the sheet metal casing.

• Main sizes: M3, M4, M5, M6, M8, M10 (M3 series being most common)
• Hexagonal column dimensions: 5, 6, 8, 10, 12, 15 mm
• Material options: Copper, stainless steel, fast cutting steel

Carbon steel is an iron-carbon alloy containing 0.0218% to 2.11% carbon, typically with small amounts of silicon, manganese, sulfur, and phosphorus. Higher carbon content increases hardness and strength while reducing plasticity.

Cost Advantage: Carbon steel is significantly more economical than stainless steel due to its simpler composition of primarily iron and carbon, without expensive alloying elements like chromium or nickel.
