Neodymium Countersunk Ring Magnet - 25mm (OD) x 10mm (H) | Countersunk 12mm/6mm (ID) | N38 | NORTH

Magnetic Product Description:

This Rare Earth Countersunk Ring Magnet has an outside diameter of 25mm, an inside diameter of 12mm to 6mm and a thickness of 10mm. It has a pull force of 15.8kg. It is identified by the magnet part number NRCS2510ID6N.

Uses for our Rare Earth Countersunk Ring Magnets:

This type of Neodymium Ring magnet has a central void that allows it to be attached to another surface with a countersunk, flat head screw. These surfaces can include timber, masonry, aluminium and other ferrous and non-ferrous materials. The countersunk fixing hole determines which side of the magnet is attached to a surface and also which magnetic pole is exposed. In the case of this item, it is North. Once attached, the ring magnet can then bond with a metal plate or steel washer that has been attached to a different surface.

This product can also be purchased with an opposing South facing pole that will also be attracted when attached to another surface. Two ring magnets with opposing poles can be screwed into place on different surfaces so they can bond with each other magnetically.

Whether you use this countersunk ring magnet to attract a metal plate, a steel surface or an identical ring magnet with an opposite South pole, the bond will be strong and reliable. However, Neodymium material is inherently brittle and will crack if screwed into position too tightly or when the magnets or surfaces are allowed to collide together. Ideally, this type of magnet should be recessed into timber or similar type of surface at a depth greater than 10mm so the timber protects it from direct contact or impact damage when the opposing surfaces bind together. Used in this way, the magnets are suitable for doorstops, holding and storing tools and equipment, timber cabinetry closure systems and many other applications where a magnetic hold is desirable but metal surfaces are absent.

Neodymium ring magnets that screw into position are practical tools that are found in many environments including agriculture, manufacturing, transport, skilled trades, construction and even the arts.
