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.

Primary Applications

Hexagonal standoffs are extensively used in computer hardware and circuit board industries. When installed, one end screws into the locked object while the hexagonal column remains exposed, enabling secure fastening 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.

Standard Specifications

Main specifications include:

  • Thread sizes: M3, M4, M5, M6, M8, M10 (M3 series being most common)
  • Hexagonal column sizes: 5, 6, 8, 10, 12, 15 mm
  • Materials: Copper, stainless steel, and fast cutting steel
Carbon Steel Properties

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

Classification of Carbon Steel
  • By Use: Carbon structural steel (engineering/construction and machine manufacturing), carbon tool steel, free-cutting structural steel
  • By Smelting Method: Open hearth steel, converter steel
  • By Deoxidation: Boiling steel (F), killed steel (Z), semi-killed steel (b), special killed steel (TZ)
  • By Carbon Content: Low carbon steel (≤0.25%), medium carbon steel (0.25%-0.6%), high carbon steel (≥0.6%)
  • By Quality: Ordinary carbon steel, high-quality carbon steel, premium steel
Cost Considerations

Carbon steel is generally more cost-effective than stainless steel due to its simpler composition of iron and carbon, without the additional alloying elements (chromium, nickel, manganese) that increase stainless steel's cost.

Stainless Steel Comparison
Composition Differences

Stainless steel contains at least 10.5% chromium by weight, providing corrosion resistance. Additional elements like nickel, molybdenum, and nitrogen enhance properties further.
