The size of neodymium block countersunk magnet
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.

What is size tolerance of block countersunk magnet?
For block magnet tolerance, whose Length & Width is +/-0.1mm, Thickness/Height is +/-0.05mm. Of course, we can custom the tolerance according to your requirements.

Magnetizing direction of block countersunk magnet
For a block magnet of F30×20×3mm, the magnetizing direction is the direction of 3, which is the thickness (height) direction of magnetization. The N pole & S pole is on the two largest surfaces, that is, the 30×20mm surface, one side is the N pole, and the other side is the S pole.

What is a block countersunk magnet used for?
A.Life consumption: clothing, bag, leather case, cup, glove, jewelry, pillow, fish tank, photo frame, watch; B. Electronic product: keyboard, electronic cigarette, display, smart bracelet, computer, mobile phone, sensor, GPS locator, Bluetooth, camera, audio, LED; C. Home-based: Lock, table, chair, cupboard, bed, curtain, window, knife, lighting, hook, ceiling; D. Mechanical equipment & automation: motor, unmanned aerial vehicles, elevators, security monitoring, dishwashers, magnetic cranes, magnetic filter.

Safety Warning:
1. Make sure keep the magnets are out of reach children and pets,it is not a TOY, and small magnets will pose a choking hazard.
2. Watch your fingers, as they are very strong magnets, which are difficult to pull apart and fly together quickly from far away, so it is very easy to pinch fingers between attracting poles.
3. Keep the magnets far way from medical devices, electronic products,and magnetic media, as our magnets have strong magnetic fields which may affect and/or disrupt the functioning of these medical devices,electronic products,and magnetic media.
4. Magnets are fragile, they can crack, chip, or shatter if allowed to slam against each other. so make sure handle with care, eye protection glasses.
