Product Overview

These 1.26" x 1/4" N52 Countersunk Neodymium Disc Magnets are engineered for applications that require maximum holding power and secure screw mounting. The large 1.26-inch diameter provides an expansive magnetic contact surface, while the 1/4-inch thickness delivers exceptional magnetic strength with a pull force of over 37 pounds. The dual-sided countersunk design allows the magnet to be installed from either side, making it ideal for professional installations that require flexibility and a clean, flush appearance.

Each magnet features precision-machined 0.36" × 0.18" 90° countersunk holes designed to accept #8 flat head screws. Because both sides are countersunk, the magnet can be mounted in either orientation while keeping screw heads recessed below the surface for maximum contact and a professional finish.

Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets provide the highest commercially available magnetic strength. The durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating offers excellent protection against corrosion, scratches, and chipping while maintaining a bright, polished finish.

What Is a Countersunk Neodymium Disc Magnet?

A countersunk neodymium disc magnet is a permanent NdFeB (Neodymium-Iron-Boron) magnet with a precision-machined center hole that allows it to be securely fastened using flat head screws. Unlike adhesive-mounted magnets, countersunk magnets provide a permanent mechanical mounting solution that is both stronger and easier to service.

This model features dual-sided countersunk holes, allowing installation from either face without sacrificing a flush finish. It is magnetized through its 1/4-inch thickness (axially magnetized), placing the magnetic poles on the two flat circular faces for maximum holding performance.

Neodymium magnets are also commonly known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.

How Strong Is This Magnet?

This 1.26" × 1/4" N52 countersunk disc magnet produces over 37 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.

Actual holding force depends on several factors, including:

  • Surface material
  • Steel thickness
  • Contact area
  • Air gap
  • Mounting method
  • Environmental conditions

For maximum holding performance, mount the magnet securely using #8 flat head screws against a clean, flat steel surface.

Note: Pull force values are estimates based on ideal laboratory conditions. Actual performance should always be verified for your intended application.

Common Questions About This Magnet

What is the pull force?

This magnet provides over 37 pounds of pull force under ideal testing conditions.

Is N52 stronger than N35 magnets?

Yes. N52 is the strongest commercially available neodymium magnet grade and delivers substantially greater magnetic strength than N35 magnets of the same size.

Can this magnet rust?

The Nickel-Copper-Nickel triple-layer coating provides excellent protection against corrosion. However, if the coating is damaged and moisture reaches the magnet, corrosion may occur over time.

Can it be used outdoors?

Yes. It performs well outdoors, but additional sealing is recommended for prolonged exposure to saltwater or extremely humid environments.

What direction is it magnetized?

This magnet is magnetized through its 1/4-inch thickness (axially magnetized), with the north and south poles located on the two flat circular faces.

Do I need to align the poles when installing multiple magnets?

Yes. When using multiple magnets together, verify the polarity before installation to ensure the magnets attract rather than repel each other.

Do you offer bulk discounts?

Yes. Contact Super Magnet Store for wholesale pricing and volume discounts on large quantity orders.

Safety Notice: These magnets are extremely powerful. Keep them away from children, pacemakers, hard drives, credit cards, and other sensitive electronic devices. Always review magnet safety guidelines before installation.
