Product Overview
These 1.26" x 1/8" N52 Countersunk Neodymium Disc Magnets combine exceptional magnetic strength with the convenience of secure mechanical mounting. The large 1.26-inch diameter provides an expansive magnetic contact area, while the low-profile 1/8-inch thickness makes these magnets ideal for flush installations where space is limited. Delivering over 20 pounds of pull force, they provide dependable holding power for a wide range of industrial, commercial, and DIY applications.
Each magnet features a precision-machined 0.355" x 0.195" 82° countersunk center hole designed for use with #8 flat head screws. The tapered countersink recesses the screw head below the magnet surface, allowing for a clean, professional installation while maximizing magnetic contact.
Manufactured from premium N52 grade NdFeB (Neodymium-Iron-Boron), these magnets deliver the highest commercially available magnetic strength. A durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating provides excellent protection against corrosion, scratches, and chipping while maintaining a smooth, polished metallic 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 mounted using a flat head screw. This design eliminates the need for adhesives while providing a strong, permanent mounting solution.
This magnet is magnetized through its 1/8-inch thickness (axially magnetized), placing the north and south poles on the two flat circular faces. Countersunk disc magnets are commonly used in woodworking, cabinetry, industrial fixtures, automation equipment, displays, and custom fabrication.
Neodymium magnets are also known as Neo magnets, NdFeB magnets, NIB magnets, or super magnets.
How Strong Is This Magnet?
This 1.26" x 1/8" N52 countersunk disc magnet delivers approximately 20 pounds of pull force under ideal laboratory conditions using a thick, clean steel surface.
Actual holding force depends on:
- Surface material
- Steel thickness
- Contact area
- Air gap
- Mounting method
- Environmental conditions
For best performance, install the magnet using a #8 flat head screw and mount it 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 approximately 20 pounds of pull force under ideal testing conditions.
Is N52 stronger than N35 magnets?
Yes. N52 is the strongest commercially available neodymium grade and provides significantly greater magnetic strength than N35 magnets.
Can this magnet rust?
The Nickel-Copper-Nickel triple-layer coating offers excellent protection against corrosion. If the coating becomes damaged and moisture reaches the magnet, corrosion may occur over time.
Can it be used outdoors?
Yes. However, additional sealing is recommended for long-term outdoor, marine, or high-humidity environments.
What direction is it magnetized?
This magnet is magnetized through its 1/8-inch thickness (axially magnetized), with the north and south poles located on the two flat circular faces.
