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. Neodymium countersunk magnets 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.
These Neodymium Shallow Pot Magnets feature a countersunk hole to accommodate screw fixings. They are ideal for applications where magnets are used closing mechanisms, where the screw head must be concealed, such as cabinet doors, drawers, gate latches and door holdings.

Countersunk Pot Magnets for Shop Fitting Applications
They are also ideal for other applications such as shop fitting where magnets are used for attaching shelving, signage, lighting systems and window displays. Neodymium is the perfect material for these applications as it gives a high magnetic strength to size ratio, hence a small magnet can be used in applications where space is limited. The countersunk hole in the magnet can accommodate anything from M3 to M5 screw head size depending on the magnet size. The countersunk magnet range is available in a number of sizes,
Neodymium NdFeb Shallow Pot Magnets with Countersunk Hole usually takes the surface coating with chrome/nickel/zinc/silver/gold/epoxy and the for the body shape sunk in like the regular shape and irregular shape, all these different requests based on clients’ special customized requests in different industrial area .if you needs more please find us which is a famous powerful magnet manufacturer here in Guangdong China.

This neodymium magnetic disc has a diameter of 50mm and a height of 25mm. It has a magnetic flux reading of 4664 Gauss and a pull force of 68.22 kilos.
Strong magnets, like this Rare Earth disc, project a powerful magnetic field that is capable of penetrating solid materials such as timber, glass or plastic. This ability has practical applications for tradespeople and engineers where strong magnets can be used to detect metal or become components in sensitive alarm systems and security locks.
Solving a countersunk magnet offset involves addressing any misalignment or unevenness between the magnet's countersink hole and the screw head, which can lead to an offset appearance. Here's how you can solve countersunk magnet offset issues:
Gauging the thickness of a countersunk magnet involves measuring the distance from one flat side of the magnet to the other flat side, taking into account the depth of the countersink hole. Here's how to gauge the thickness of countersunk magnets:
Here's how you can work on developing countersunk magnets yield:
