Product Description

Permanent neodymium pot magnet with internal thread 
This permanent magnet pot assembly is made by sticking a permanent magnet (using new materials and standard grade) into a steel cup that with the external thread or male thread. Steel nut and screw cap can be fixed on the external thread. We usually glue neodymium disc magnets into the steel cups. The steel cups can not only protect the disc NdFeB magnet but also ensure the NdFeB disc magnets strongest magnetic force and holding ability. The steel cup of the pot magnets with eyelet can be made by lathing or punching. We have both two kinds of pot magnets with closed hook for sale.

These pot magnets have a threaded bushing on the opposite side of the magnet. In the existing internal thread, you can screw in screws or other parts with an external thread. These magnetic plates form the basis of our hook magnets / eyelet magnets, which you can of course also get from us.

The internal threaded stud pot magnet is also known as a female threaded stud pot magnet. They consist of a ferromagnetic mild steel cup containing a magnet (usually a disc magnet) with a ferromagnetic mild steel stud / boss / bush mounting at the back of the pot magnet into which a threaded hole has been made.

These Neodymium pot magnets are known as female threaded stud pot magnets because the internal threaded hole could take pot magnets with threaded bar at the back (external threaded stud pot magnets /male threaded stud pot magnets) as well as bolts.
Because the mild steel is stud / boss is threaded there is decent thread length allowing reasonably high torque to be applied to securely hold each pot magnet in place. These pot magnets have a screw socket, into which you can screw hooks, eyelets, etc. Steel rings and hooks can be screwed into the threaded hole.
To meet the needs of different holding force, we provide a wide size range, the diameter of the internal pot magnets is from 12mm to 75mm, the thickness is from 5mm to 18mm.The size of threaded hole is from M3 to M10.

The testing picture of this neodymium pot magnet with internal thread for your reference:
Remark: the strength is the vertical magnetic pull-force which make the magnet pull away from the 1.18'' thickness steel plate of a tester under ideal condition, it does not mean the actual weight which the magnet can lift the actual pull force will vary mainly depending on the following variables:
A: Steel thickness (the thicker the steel is, the stronger the pull force)
B: Attracting position (the farther beyond the center of gravity of the attracted object, the lower the pull force)
C: Pulling direction ( the smaller the angle taking 90°as a standard, the stronger the pull force), the pull force in horizontal direction is only about one third of that in vertical direction)

Following is our standard sizes of neodymium pot magnet with internal thread for your choice, if there is no size you need or some different requirement, please contact us to custom:
Package of pot magnet with countersunk hole: 
Shipment: Pot Magnet can be shipped by Air, Express, Truck and by sea. But it must be shielded if by air or Express. 
How to promise the quality: Quality is our culture! To ensure our quality, all pot magnets are produced with 100% new standard material rather than recycle or bad material. Besides our professional QC department will inspect the magnet for each stage, including magnet grade, coating, dimension, tolerance and pulling force for pot magnet, magnetic hook, fishing magnet or other magnetic assemblies. So that our magnet pass rate is as high as 99.5%.
Sample:Sample of pot magnet is available to provide within 1-2 days if we have it in stock. Otherwise, it takes 5-7days to custom.
MOQ: Usually we don't require special MOQ of regular magnet or pot magnet for you, small order is available to accept. If you ask for special custom magnet or pot magnet and it needs mold to produce, MOQ is decided as product details.
Custom service: Custom service is our advantage. Multimagnets has a professional technical team to support our customers. We can provide professional CAD drawing, strength simulation of magnet / pot magnet, even that Multimagnets can assist you to design a new magnet. For some Amazon customer, Multimagnets always provide free labeling and professional photos taking.
