Screw-on neodymium magnets round, square, with one or two holes

Countersunk magnets as disc or block magnet featuring a countersunk hole

Countersunk Hole Magnets are very popular amongst tradespeople and fabricators. Frequently used as magnetic closures for cabinets, gates and door latches and any other hidden magnetic closure mechanism. The hole allows the Neodymium magnet to be secured on any surface with a screw or bolt. Rare Earth magnets are brittle and can break easily if mishandled; countersunk magnets provide a convenient means of securing the magnet without causing damage. Countersunk magnets are commonly used for shop-fitting, shelving and lighting fixtures, window and screen displays as well as to hold and hang signage.

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 N42 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 and more.

Are Countersunk Magnets available in different shapes?

Countersunk magnets come in all shapes and sizes depending on the requirements. The most common shape is disc and block magnets, however, they can be cylindrical or spherical. They can also be completely customised to neatly fit inside of an intricate design. We can customise these magnets to your exact specifications of size, shape, strength and coating.

Are Countersunk Magnets magnetic on both sides?

Countersunk ring magnets are magnetic on the countersunk face and magnets are magnetic on both sides.

What is the difference between countersunk magnets and pot magnets?

Countersunk magnets and pot magnets are similar due to them both having holes that allow for screws. However, unlike ordinary countersunk magnets, pot magnets have a steel shell that covers the flat side of the magnet. The shell provides a protective barrier that partially protects the magnet from damage and corrosion, however, it is not magnetic on the back.

Uses of Countersunk Neodymium Magnets

Neodymium is a rare earth magnet and these magnets are the strongest in the world. They are comprised of Neodymium, iron and boron and they generate a powerful magnetic field like no other. The attributes of Neodymium magnets give you an almost endless list of practical uses. Rare earth countersunk Neodymium magnets, or countersunk ring magnets, are specially designed to be drilled or fixed into place. Countersunk screw magnets come in various shapes such disc magnets, block magnets and pot magnets. All of these shapes have a countersunk hole that fits a screw head flush.
