Standoffs and Spacers

Standoffs and spacers are fasteners used to connect, position and raise panels and PCB assemblies above other electronic components. Standoffs have a round or hexagonal shape with ends that are either internally threaded (female) or externally threaded (male). Spacers are cylindrical or hexagonal with an unthreaded interior that allows the entire bolt to pass through the center.  Cylindrical standoffs and spacers can be easily tightened by hand and hexagonal standoffs are designed to be tightened with a wrench.

Custom Standoffs and Spacers Available in Various Lengths and Sizes, and in Materials Including:

  • Nylon: nonconductive, insulative, protects wiring
  • Steel: exceptional strength and durability
  • Stainless steel: resists chemicals and corrosion, high strength-to-weight ratio
  • Brass: corrosion-resistant, conductive, non-magnetic
  • Aluminum: strong, lightweight, noncorrosive, non-magnetic, excellent temperature resistance

Circuit Board Standoffs and Spacers for Computers and Electronics

Female Female Standoffs 

Female Female Standoffs have a round or hexagonal shaft with an internally threaded opening at both ends. Available in 1/8”, 1/4” and 3/16” diameters and lengths up to 1”. Thread sizes vary depending on style.

Male Female Standoffs

Male Female Standoffs feature a hexagonal or cylindrical shape and have one internally threaded end and an externally threaded post at the other end. Available sizes for male female standoffs include 3/16”, 1/4”. 5/16” and 1/2” diameters and lengths up to 4”, depending on the style chosen.

Metric Female Standoffs 

Metric Female Standoffs are hex-shaped with two internally threaded ends. They are available in 4.5mm and 6mm options in a variety of lengths up to 15mm. Thread and pitch dimensions vary depending on style.

Metric Male Female Standoffs 

Metric Male Female Standoffs have a hexagonal shaft and are offered in 4.5mm and 6mm options with lengths up to 25mm. They feature an internal thread at one end and a threaded external post at the other end.


Spacers are unthreaded fasteners with a cylindrical or hexagonal body. They are offered in 3/16”, 1/4”, 5/16”, 3/8” and 1/2” diameter options in various lengths up to 1”.  Our spacers accommodate screws up to size 10.

Circuit Board Standoffs and Spacers Considerations for the Right Selection 

Custom standoffs and spacers are offered in a wide range of sizes and lengths for electronics applications. There are several factors to consider when selecting your spacers, including:
  • Thread type (also called gender): standoffs and spacers are offered in female-female, male-female and male-male configurations.
  • Shape: cylindrical spacers and standoffs can be tightened by hand, but hexagonal standoffs must be tightened using a wrench
  • Body length: this determines the amount of spacing between the PCB assemblies and components
  • Body diameter and thread size: to ensure the spacers match your screw thread type and diameter
