Neodymium Block Magnet - 20mm x 10mm x 4mm | Countersunk 4mm-8mm hole

Neodymium Block Magnet Description:

These Neodymium Countersunk Magnets have a strong pull force and a countersunk hole in the centre, making them one of the most versatile magnets in our stock. Made from high-quality Rare Earth Neodymium magnetic material for maximum strength, this Neodymium magnet is in a block shape with a countersunk 4-8mm hole in the centre. It has a 20mm length, 10mm height and a 4mm thickness, as well as a pull force of 3.5kg.


Uses for our Countersunk Rare Earth Bar Magnets:

This Rare Earth Block Magnet is a great all-purpose magnetic tool for joining and holding due to its super-strong magnetic pull and the convenient countersunk hole in the centre of the block. Strong Neodymium Bar Magnets are easy to fasten or mount onto a surface or wall with the addition of a screw through the centre hole. This Neodymium Rare Earth Magnet is axially magnetised and can easily attach to a metal object or surface. The powerful and small magnet has an impressive pull force relative to its small size.

Worked well

I used the block as one half of a magnetic latch for a tool box. The other half comprised three short lengths of fencing wire inserted end-on into the mating surface.

works well , but they are brittle .

Used these magnets to hold extra bits in my drill driver box .

They work great , but I broke the first one by tightening the screw with the impact driver , don't do this , tightened with a screwdriver no problem .

Good but .....

Magnets arrived very quickly but arrived with 2 cracked magnets in the centre of the pack. Attached the surviving magnets to the underside of a small key safe that can now solidly attach to the underneath of the car while parked.

Hi Stephanie, thank you for your feedback! Sorry to hear two magnets arrived cracked, we package all our magnets with a generous amount of bubblewrap to prevent any breakages during transit but if you'd like to send us email with a photo of the cracked magnets along with your invoice number we can arrange a replacement. Kind Regards, AMF Magnetics.
