Neodymium Countersunk Magnets as Disc or Block Magnet

Countersunk Magnets - Neodymium Cup Magnets with Mounting Hole

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. 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.

Countersunk magnets are available with either pole on the magnetic face so that they can be used as a pair to attract or repel. If you are using two magnets to attract you need to make sure the opposite poles are facing each other as identical poles will repel!

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.

Neodymium countersunk magnets are magnets that have a conical recess or depression on one or both sides, enabling them to be fastened to another surface with a screw.

Neodymium countersunk magnets can be used to create a strong and reliable fastener, making them ideal for securely attaching magnets onto both magnetic and non-magnetic surfaces including wood, plastic, brass, copper, rubber, and aluminum. That makes these magnets popular in construction, woodworking, and industrial applications.

The countersunk hole enables a standard screw to be flush mounted into the magnet to securely fasten it into doors, closets, cabinets, chests, toolboxes, displays, signs, panels, art frames, and other hidden closure or attachment applications.

• 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 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.

Function of Pot Magnets (Neodymium Magnets) with Threaded Stud

• Principle: The strong neodymium magnets are embedded in a steel pot. The steel pot increases the adhesive force of the magnet on direct contact with a thick iron surface. If there is no direct contact with the counterpart, or if the steel plate is thin, painted or rough, you can strain it much less.
• Shear force: The indicated adhesive force was measured perpendicular to the surface to which the magnet should stick. It takes a lot less strength to move the magnet sideways. Therefore, you can strain a pot magnet much less if you use it on a wall as opposed to using it on the ceiling.
• Rust: These magnets are not rust-proof and therefore intended for dry indoor use.

Neodymium countersunk magnets are ideal for consumer and industrial applications requiring very high magnetic strength. They are routinely used to secure, position, or mount equipment and devices. Common devices and applications that utilize neodymium countersunk magnets include:
