Round spacers are unthreaded fasteners commonly used with circuit boards, furniture, signage and gear assembly to maintain space between components. They slide over bolts or screws. Aluminum round spacers are nonmagnetic and corrosion resistant and lighter than steel, making them useful when a lightweight fastener is needed.
