Countersunk Magnets - Neodymium Cup Magnets with 90° Mounting Hole

Countersunk Magnets, also known as Round Base, Round Cup, Cup or RB magnets, are powerful mounting magnets, 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.

  • 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 used for any application where high-magnetic strength is required. They are ideal for lifting, holding & positioning, and mounting applications for indicators, lights, lamps, antennas, inspection equipment, furniture repair, gate latches, closing mechanisms, machinery, vehicles & more.

We carry a large inventory of Neodymium Countersunk Magnets, not all of which are shown on this website. Contact us today or send us a request for quote and let us know what you are looking for.

* $15.00 total minimum order (excluding shipping & tax if applicable) - Items can be combined to reach the minimum amount.

 

Neodymium Countersunk Magnet Approximate Pull Info

The approximate pull info listed for Neodymium Cup Magnets is for reference only. These values are measured under the test conditions where the magnet is attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain other environmental conditions can significantly reduce the pull force. Please be sure to test the pull in your actual application. 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. top

Neodymium Countersunk Tolerance Info

Standard tolerances are +/- 0.005" on both diameter and thickness dimensions. top
