The nylon round spacer provides resistance to abrasion, corrosion, and many chemicals and solvents. The material is a strong yet lightweight plastic and is nonconductive. Nylon can either absorb or lose moisture, which may alter its dimensions and mechanical properties.Spacers are unthreaded tubes that separate, space, or connect components within a system to ensure proper placement. Round spacers (also called clearance spacers) are the standard shape, while hex and square styles have flat sides that can be gripped with a wrench or pliers. Saddle spacers (also called saddle washers) and angled spacers have one flat end and one end that accommodates a curved or an angled component, respectively. Panel spacers are another type of spacer that provides a decorative or architectural mounting option for glass or display panels. Captive panel spacers have one toothed edge that inserts directly into the panel and hooks in to securely hold the panel away from the mounting surface.
