Spacer

A spacer is a plain sleeve or block that sits between two parts to hold a gap. It keeps distance and can spread load over a wider area.

A spacer keeps two parts at a set distance apart. It fits over a bolt, screw or shaft and can be round or hexagon in shape. The spacer is placed between the parts and is held by the fastener.

Spacers are often made in steel, stainless steel, aluminium, brass or nylon. The material affects strength, corrosion resistance and electrical insulation.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and a material certificate if needed. On receipt, check the bore, outside diameter and length. Look for burrs, cracks or uneven ends.
