Countersunk Steel Washer 32mm x 3mm

Countersunk Steel Washer – 32mm x 3mm

The Countersunk Steel Washer – 32mm x 3mm is a precision-machined steel mounting plate designed to provide a secure fixing point for countersunk magnets, pot magnets, magnetic catches, and other magnetic fastening systems. Measuring 32mm in diameter and 3mm thick, this heavy-duty steel washer creates an ideal magnetic target surface, significantly improving the holding performance of permanent magnets where a ferrous mounting surface is unavailable.

Manufactured from high-quality steel, this countersunk washer features a centrally positioned countersunk hole, allowing it to be mounted flush with a countersunk screw for a neat, professional finish. Once installed, the screw head sits below the washer's surface, ensuring maximum contact between the magnet and the steel washer for optimal magnetic attraction.

Ideal for use in cabinetry, furniture manufacturing, shopfitting, industrial equipment, signage, access panels, display systems, and DIY projects, this steel washer offers a simple and cost-effective solution for creating magnetic closures and removable fixing points. It is commonly paired with neodymium countersunk magnets, pot magnets, and magnetic catches to form strong, reliable magnetic fastening systems.

Whether you're designing magnetic doors, removable covers, inspection panels, display fixtures, or custom magnetic assemblies, the 32mm x 3mm Countersunk Steel Washer provides a durable and dependable magnetic contact surface for professional and industrial applications.

Why Choose a Countersunk Steel Washer?

The 32mm x 3mm Countersunk Steel Washer is specifically designed to maximise the effectiveness of magnetic mounting systems by providing a flat, ferrous surface that magnets can securely attract to. Rather than relying on direct contact with timber, aluminium, plastic, or other non-magnetic materials, this washer creates a dedicated steel target that significantly improves holding strength and consistency.

Its flush countersunk design ensures the fixing screw sits below the contact surface, allowing the magnet to make full contact with the steel washer for maximum magnetic performance. This not only improves holding force but also reduces wear and provides a cleaner, more professional installation.

Suitable for both commercial and residential projects, this steel washer is an excellent choice for magnetic catches, removable panels, access doors, display systems, and countless custom magnetic applications where reliable holding performance is essential.

Please Note

This product is not a magnet. It is a steel mounting washer designed to provide a magnetic contact surface for permanent magnets.

For maximum magnetic holding strength, ensure the washer is mounted securely to a flat surface using an appropriately sized countersunk screw. Actual holding performance will depend on the strength and size of the magnet used, alignment between the magnet and washer, surface condition, air gap, and mounting configuration.

Steel components may develop surface corrosion if exposed to prolonged moisture or outdoor environments unless appropriately protected. If the application is outdoors or in corrosive environments, consider suitable protective finishes or regular maintenance to maximise service life.
