Product Description
Strong Pot Magnets with Hole Ø 20 X 6 mm, Powerful Rare Earth Neodymium Cup Magnets with Borehole, China Holding Magnets , Through Hole NdFeB Magnetic Pots
Strong Pot Magnets with Hole Ø 20 X 6 mm Part No.HS-NB20-1 by HSMAG Features :
Material: Housing steel and Magnetic core sintered neodymium ring magnet.
Version: Housing, galvanized. Magnet, Ni coated or Zn coated
Note: Shallow flat pot magnets with cylindrical hole. These magnets are pressed or glued into the receiving holes.
Hairline cracks in the magnetic material are unavoidable for technical reasons in the D=20 version. They do not impair the attracting function of the magnets in any way.

An introduction to Threaded Through Hole
Threaded Through Hole
The Pot Magnet with Threaded Through Hole Mounting consists of a steel disc with a ring milled out for a ring magnet to be inserted plus a tapped through hole to allow a M4, M6 or M8 threaded bar or bolt to be screwed through. The design is compact and extremely robust. The through hole allows the possibility of a bolt or threaded bar to be screwed past the magnet face to prise the Pot Magnet with Threaded Through Hole Mounting away from the structure to which it is magnetically held against.
The Pot Magnet with Threaded Through Hole Mounting uses ferrite magnets and the steel casing is zinc or chrome plated for corrosion protection. The ferrite Pot Magnet can be used up to +180 degrees C but may start to show some signs of weakening (demagnetisation) when used in sub-zero conditions e.g. -10 to -20 deg C but the actual design and application determines at what temperature demagnetisation may be noticed.
We also offer a Pot Magnet with Threaded Through Hole Mounting with a Stainless Steel (SS304) casing. This does not require any plating and is naturally corrosion resistant.
The Pot Magnet with Threaded Through Hole Mounting range exists in 25mm to 80mm diameter size with maximum pull forces from 3.6kg up to 55kg.

Rare Earth Neodymium Pot Magnets / Neodymium Mounting Magnets are extremely useful for holding, actuating, pulling, hanging, locating, separating, retrieving…the list never ends!
SOME OF THE MANY USES FOR POT MAGNETS INCLUDE:
Holding temporary safety or advisory flags on railways and industrial sites
Concreting applications where reo off-cuts need removing before a slab is poured
Keeping doors open or closed
Document holding on office or factory walls
Switch actuation
Cable hanging
Stringline tie downs on building sites
Sign holdings
