The Brass Components

Brass Round Metric Spacers

Brass Round Metric Spacers, otherwise known as Cylindrical Spacers, are designed to offer additional clearance between two components whilst increasing both airflow and cooling.

These spacers feature a cylindrical body with a hollow, unthreaded interior. The exterior surface is smooth which provides low-friction and easy rotation – suitable for use as bushings, rollers or glides.

Brass Round Metric Spacers offer anti-rust and water resistant properties for internal and external applications. They are also non-magnetic and offer some electrical conductivity.

Typically manufactured from Brass Nickel Plated as standard. The Nickel Plate provides a decorative silver appearance – ideal if the spacer is visible after installation – as well as increased corrosion resistance compared to non-plated Brass. This is beneficial for use in potentially corrosive environments e.g. coastal locations.

Available in sizes ranging from 2.2mm (M2) to 6.4mm (M6) as standard, with lengths from 1mm to 50mm. Minimum order quantities apply.

Other materials are available to order including Stainless Steel, Nylon, Aluminium and Titanium. We also supply a huge range of Brass Fasteners here at Fastenright.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacturer , modifications and custom parts made to drawings.
