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.

Honsen offers all kinds of countersunk magnets in regular blocks and discs as well as other custom shapes. Contact us or send us a request for countersunk magnets.

Neodymium Countersunk Magnet Pull Force

The pull force of a Neodymium Cup Magnets is decided by magnet materials, coatings, rust, rough surfaces and certain environmental conditions. Please be sure to test the pull force in your actual application or let us know how you’ll test it, we’ll simulate the same environment and make the testing. 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.

Where to Use Neodymium Countersunk Magnets ?

It is necessary to use neodymium countersunk magnets in accordance with the manufacturer’s instructions. Their usage ranges from science category demonstrations to interest crafts, stud finders, or organizers. They can additionally be used on steel device containers to stick small tools to them. However, if wrapped on the floor tiny countersunk magnets can lose a little pull force.

As we all know, neodymium countersunk magnets are magnets shaped like rings with a gap in the middle. Their magnetic pressure is very sturdy no matter the measurement of the magnet. They are acknowledged to be five to seven times greater than ceramic (hard ferrite) magnets. The countersunk neodymium magnets have much domestic and business uses. They can only work with countersunk screws as they are very brittle and fragile magnets.

When two magnets are stuck together, possibly to combine their full force, they won’t separate from each different that easily. It is wiser to slide them apart one at a time to avoid accidents. To stick them collectively again, a user has to be cautious now not to let them leap or fly. Instead, they need to firmly maintain them and reverse the sliding process. This will avoid skin pinching and magnet breakage. If they slam together, their sharp edges will cut or break.
