A standoff is a specialized fastener with internal thread at one end and external thread at the other end. In broader terms, it also includes screws with internal threads at both ends. Featuring a hexagonal shape, standoffs serve dual purposes of fastening and isolation. Typically manufactured from hexagonal copper rods, they are also commonly referred to as copper columns, hexagonal copper columns, copper isolation columns, or copper gasket columns.
Applications: Hexagonal standoffs are primarily used in computer hardware and circuit board industries. When one end is screwed into the locked object, the exposed hexagonal column can secure or isolate other components.
Standard Specifications: Main specifications include M3, M4, M5, M6, M8, and M10, with hexagonal column sizes ranging from 5, 6, 8, 10, 12, to 15 mm (M3 series being most common). Materials include copper, stainless steel, and fast cutting steel.
Alternative Names: Also known as yin-yang studs, these components feature internal thread at one end and external thread at the other, both with hexagonal profiles for effective fastening and isolation.
Typical Use Case: In computer mainframes, the external thread connects to the motherboard while the internal thread isolates the motherboard from the sheet metal casing.
Brass Composition: An alloy of copper and zinc. Ordinary brass contains only these two elements, while special brass incorporates additional alloying elements.
Brass Applications: Valves, water pipes, air-conditioner connectors, and radiators due to its excellent wear resistance.
Brass Classification by Zinc Content:
Copper Grades:
Special Brass Varieties: Alloyed with elements like lead, tin, or aluminum to enhance tensile strength and machinability. Coded as H + element symbol + copper mass fraction + alloy mass fraction (e.g., HPb59-1 for 59% copper, 1% lead brass).
