No Matter you buy 1 pcs or 100,000 pcs of magnets, you can not find better service elsewhere.
strong countersunk magnet D20x3x5.2mm 

Neodymium magnets are the world's strongest magnets, compared with Samarium cobalt, ferrite magnets, and alnico magnets. 
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. 

Brand new and high quality.
The products will only be shipped after receiving a full payment. Super strong Rare-Earth magnets - once they get stuck with each other.

they are hard to break apart.
Can also be used to extend protected lithium batteries with recessed contact points.
Electrically conductive (making them suitable to extend recessed batteries).
Perfect for sticking notes on fridge doors.
Great for do-it-yourself projects.
Size:  20mm x 3mm Hole: 5.2mm .

Introduction of Great Magtech:

Advantages of Countersunk magnet

1. High Grade / High performance:
GME highest grade: N54, 52M, 50H, 48SH, 42UH, 38EH, 33AH, etc.




2. High Consistency: 
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:
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:
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:
 coating Nickel-Copper-Epoxy is typically more than 1000 hours.
