Neodymium Countersunk Magnets
Countersunk Magnets - Neodymium Cup Magnets with 90° Mounting Hole
Countersunk Magnets (also known as Round Base, Round Cup, Cup or RB magnets) are very powerful mounting magnets. They are built with neodymium magnets in a steel cup with a 90° countersunk hole on the working surface to accommodate a standard flat-head screw. The screw head sits flush or slightly below the surface when affixed to your product. Key features of neodymium countersunk magnets include:
- The magnetic holding force is focused on the working surface and is significantly stronger than an individual magnet. The non-working surface is very little or no magnetic force.
- Constructed with N35 Neodymium magnets encased in a steel cup, plated with a triple-layer of Nickel-Copper-Nickel (Ni-Cu-Ni) for maximum protection against corrosion & oxidation.
- Neodymium cup magnets are a reliable solution for any application where high-magnetic strength is required to securely fasten a magnet to an object.

Neodymium Countersunk Magnet Approximate Pull Info
*Note: The approximate pull info listed is for reference only. These values are calculated assuming the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in it's exact context. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.
Neodymium Countersunk Tolerance Info
Standard tolerances are +/- 0.005" on both diameter and thickness dimensions.
Commercial and Consumer Applications for Neodymium Countersunk Magnets
