No Matter you buy 1 pcs or 100,000 pcs of magnets, you can not find better service elsewhere.
Neodymium magnets are the world's strongest magnets, compared with Samarium cobalt, ferrite magnets, and alnico magnet.
GME Magnets offers the highest quality Neodymium magnets with consistent performance and lowest price.
Our Neodymium magnets are designed and manufactured to meet with quality standards using the latest technology.
Our Neodymium magnets are designed and manufactured to meet with quality standards using the latest technology.
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!

The magnet blocks are incredibly powerful as well as incredibly versatile.
The unique double countersunk holes (on both sides!)
in this mighty block allow it to go where a normal magnet could not.
This block is quite strong, making it a great choice for heavier holding applications. However,
if not handled properly they can break or pinch.

Introduction of Great Magtech:
Advantages of GME countersunk magnet
1. High Grade / High performance of countersunk magnet: GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.
2. High Consistency of countersunk 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 countersunk 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 countersunk 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 countersunk magnet:
coating Nickel-Copper-Epoxy is typically more than 1000 hours.
