UNIQUE DESIGN- Block magnets with a square base area and a countersunk hole. They can be fastened with a countersunk head screw.The countersunk hole enables a standard screw to be flush mounted into the magnet to securely fasten it into doors, cabinets, chests, toolboxes, displays, signs, panels, art frames and other hidden closure.
WIDELY USED - Neodymium rectangular magnets can be used for refrigerator, kitchen, shower door, office, scientific purposes, arts and crafts or school classroom and so on.
POWERFUL MAGNETS - Made of super strong magnetic material! Strong holding power and permanent neodymium magnet.
Custom Magnet Size: ( Please noted all size in mm or inch )
The size of a block counterbore refers to length (L) × width (W) × height (H)-D1/D2. Generally, F starts to represent the square.
For example: F30×20×3mm-D7.5/d3.5mm, it means that the rectangular magnet is 30mm long, 20mm wide, 3mm thick (height), counterbore diameter 7.5mm, straight hole diameter 3.5 mm generally defaults to the last number indicating the magnetizing direction of the magnet.
FAQ:
Q1. What are countersunk magnets used for?
A1. Basically, countersunk magnets are good for whenever you need to securely fasten a magnet to an object or surface. Gluing magnets works, but sometimes you need something more rigid, which is where countersunk magnets are great.
Q2. How do you install countersunk magnets?
A2. Installation is simple: Drive the screw through the hole in the countersunk magnet, drilling it flush with the top of the countersunk so there's no chance of the magnet shifting or snagging anything nearby. Finally, be careful not to over-tighten the screw, especially when using an all-magnet countersunk.
Q3. Can you cut rare earth magnets?
A3. Magnets are sintered and are therefore extremely hard and brittle. You should never attempt to cut or drill into a magnet unless using diamond tooling and coolant as the dust can be highly flammable.
Q4. Can you drill a hole in a rare earth magnet?
A4. Magnets should not be drilled as they are brittle and are likely to break during the drilling process.
Q5. Which is stronger rare earth magnets or neodymium?
A5. Rare earth magnets are made from rare earth elements found on the periodic table. Neodymium magnets are the strongest rare earth magnets and the strongest magnets in the world. What is the strongest type of magnet? Neodymium magnets are the strongest magnets in the world.
