Quick Answers
| Question |
Answer |
| How strong is this magnet? |
Over 24 lbs of pull force under ideal conditions. |
| What is this magnet made of? |
NdFeB (Neodymium-Iron-Boron) rare earth material. |
| Is this stronger than ceramic magnets? |
Yes. N35 neodymium magnets are significantly stronger than ceramic (ferrite) magnets of similar size. |
| Can it be used outdoors? |
Yes, but additional sealing is recommended for long-term outdoor or marine use. |
| What is it commonly used for? |
Screw-mounted fixtures, cabinet doors, gates, woodworking, signs, industrial mounting, machinery, and DIY projects. |
Product Overview
These 1.26" x 0.20" N35 Neodymium Countersunk Disc Magnets are designed for applications that require both powerful magnetic holding force and secure mechanical fastening. The precision-machined 90° countersunk center hole accepts a #8 flat head screw, allowing the screw head to sit flush with the magnet surface for a clean, professional installation.
Manufactured from premium N35 grade NdFeB (Neodymium-Iron-Boron), these magnets deliver over 24 pounds of pull force under ideal conditions. Their large diameter and thicker profile provide excellent holding power for cabinetry, woodworking, fixtures, displays, machinery, and industrial applications where adhesive mounting is not suitable.
Each magnet is protected by a durable Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer coating, providing excellent resistance to corrosion, chipping, and everyday wear while maintaining a smooth, polished finish.
What Is a Countersunk Neodymium Disc Magnet?
A countersunk neodymium disc magnet is a powerful permanent rare earth magnet that features a precision-machined tapered center hole for screw mounting. Unlike adhesive-backed magnets, countersunk magnets can be permanently fastened to wood, plastic, or other materials using flat head screws, creating an exceptionally secure mounting solution.
This magnet is axially magnetized through its 0.20-inch thickness, meaning the north and south poles are located on the two flat circular faces to maximize holding strength against steel surfaces.
How Strong Is This Magnet?
With an approximate pull force of over 24 pounds, this N35 countersunk disc magnet provides strong holding power for permanent installations. The large 1.26-inch diameter maximizes contact area while the thicker body produces a stable magnetic field suitable for heavy-duty mounting applications.
Actual holding force depends on several factors, including:
-
Steel thickness and material
-
Surface cleanliness and finish
-
Air gap between the magnet and steel
-
Mounting orientation
-
Operating temperature
Testing in your actual application is recommended to determine real-world performance.

Common Questions About This Magnet
What is the pull force?
Over 24 pounds under ideal testing conditions.
What size screw fits the countersunk hole?
The 0.355" x 0.195" 90° countersunk hole is designed for #8 flat head screws.
Can it rust?
The Nickel-Copper-Nickel coating provides excellent corrosion resistance, but prolonged exposure to moisture should be avoided unless the magnet is additionally protected.
Can it be used outdoors?
Yes. For long-term outdoor or marine environments, sealing the magnet or using a protective housing is recommended.
What direction is it magnetized?
This magnet is axially magnetized through its 0.20-inch thickness, with the north and south poles located on the two flat faces.
Do you offer bulk discounts?
Yes. Volume pricing is available for manufacturers, distributors, OEMs, and large production orders.
Safety Information
Neodymium magnets are extremely powerful and should be handled with care. Large magnets can snap together unexpectedly and may cause injury or damage if handled improperly. Keep away from children, electronics, medical implants such as pacemakers, and magnetic storage devices.
