Disc Countersunk Hole strong Permanent Rare Earth Magnets with Screws

Product Description

Countersunk magnet is a new generation of neodymium magnet, which has expanded the range of application, whatever this object is wooden, plastic or steel, we can also use countersunk magnet to fix in place with screws, which allows the magnet to be easily fastened into place for a temporary or permanent fixing purpose.


The countersunk magnet is available with a countersink on the north face or south face of the magnet, they can work with M4, M5, M6, M8 etc. countersunk screws. Whatever North pole or South pole is on the magnetic face, countersunk magnet can be as a pair to attact or repel when they are used. That is to say, when you are using two countersunk magnets together, like poles repel and opposite poles attract.

FAQ

Q)How material grade and magnet dimensions(L x W x H) affects the Gauss Level of magnets?

 A)Same magnet size,  Higher grade with higher gauss

   Same magnet grade, same surface area, the thicker, the  higher gauss

   Same thickness, same thickness, larger surfacearea with lower gauss

 

Q) What are neodymium magnets?
A) Neodymium magnets are a member of the rare earth family and are currently the strongest permanent magnets in the world! They are composed of neodymium, iron and boron (NdFe)
 
Q: What does pulling force mean?
A: Pulling force is a measure of magnetic strength. It is the amount of force required to remove a magnet parallel to a solid magnetic surface, such as a steel plate.
  
Q: Do I have to worry about temperature with neodynium magnets?
A: Yes. They are sensitive to heat so do not heat them above 175°F (80°C) If you do, they will begin to lose their magnetic strength. This normally applies only to industrial usage of heating the magnets, normal application will not affect the strength of the magnets.
 
Q: If I stack two neodymium magnets together, does their strength double?
A: No. It will a little smaller. For example, two magnets rated with a individual pulling force of 50 lbs will have a combined pulling force of 90 lbs when stacked together.
 
Q: Do neodymium magnets lose strength over time?
A:No. They do not naturally lose any appreciable strength and will last your lifetime!
