Spacers and standoffs are small, cylindrical or hexagonal devices used to create clearance gaps between two or more joined surfaces or components. They are typically made of metal, plastic, or ceramic, and come in a variety of sizes, materials, and finishes.
The primary distinction between a spacer and a standoff lies in the threading. Standoffs have threading at both ends, which can be either male (protruding) or female (internal). In contrast, spacers usually lack this threading. Standoffs offer various gender combinations, including male-male, female-female, or male-female options.
Spacers and standoffs are used in a wide variety of applications, including:
- Electronics: Spacers and standoffs are used to mount circuit boards, components, and other electronic devices. They help to ensure that the devices are properly aligned and spaced, and they also provide a barrier between the devices and the metal case.
- Machinery: Spacers and standoffs are used to mount bearings, gears, and other mechanical components. They help to prevent the components from rubbing against each other, and they also provide a degree of vibration isolation.
- Construction: Spacers and standoffs are used to mount pipes, conduits, and other building materials. They help to keep the materials in place, and they also provide a degree of fire protection.
