countersunk magnet for the fixing screw #6
Standard sizes ship within 2 weeks. custom-made size and grade are always available.
Neodymium countersunk magnet is special type of neodymium disc/block magnet with a hole fit for screw.
We can provide neodymium countersunk magnets for various applications.
Countersunk Magnets are often used in shelving and lighting systems, screens, window displays and signage.
Countersunk magnets are available with either pole on the magnetic face so that they can be used as a pair to attract or repel.
If you are using two magnets to attract you need to make sure the opposite poles are facing each other as identical poles will repel!

Application of the permanent magnet:
----------------------------------------------------------------------------------------------------------------
Introduction of Great Magtech:
Advantages of GME permanent magnet
1. High Grade / High performance of permanent magnet: GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.
2. High Consistency of permanent magnet:
The Cpk of Remanence (Br) and Intrinsic Coercive Force (Hcj) are much higher than 1.67.
The consistency of the surface magnetic field and magnetic flux can be controlled at +/-1%.
3. High Working Temperature of permanent magnet:
GME magnets can satisfy the working temperature requirements with excellent temperature resistance.
The AH series with 40 kOe super-high coercive force can replace Smco magnets in most applications.
4. Low Weight loss of permanent magnet:
GME super-high magnets have a long lifetime with the following specifications; PCT: 130C，humidity 100%，
vapor pressure 2.7bar, 20days，average low weight loss <2 mg/cm².
5. High anti-corrosion of permanent magnet:
coating Nickel-Copper-Epoxy is typically more than 1000 hours.
