Self-Retaining Spacers

Self retaining spacers are used to insulate the heads of screws on a PCB (printed circuit board), while providing the desired spacing between the chassis and the PCB.

How do self retaining spacers work?

Self retaining spacers are similar to round spacers or hex spacers, but with special inside diameters that are designed to grip the screw's outside shank. They have snap-in mounting mechanisms that ensure the required space is maintained even when a screw is removed.

The snap-in standoff snaps into the PCB so that it’s locked in position. Self retaining spacers are designed to raise stacked sections, reduce physical contact between two components and create enough space for heat dissipation. Self retaining spacers are available in several spacing heights to suit different applications.

What are self retaining spacers used for?

Self retaining spacers are used in applications that require precise control of product lengths and dimensions. Some typical applications include:

  • PCBs
  • Cable assemblies
  • Telecommunication equipment
  • Computer enclosures
  • Electronic automotive assemblies
  • LED positioning
