All Magnets > Magnets with Holes


Magnets with holes are also referred to as "Ring Magnets", but that does not seem quite right to me when the holes are relatively small.

Most of these magnets have countersunk holes, so they can be mounted without the screws interfering with the face of the magnet.
A small amount of magnetic strength is lost if steel screws are used. To retain full strength, use stainless steel or brass screws.

For a good online source of screws, see under "Stainless Steel Fasteners" at Steelmasters.


Sliding scale quantity discounts are available, beginning with 10% for purchases of 3 packs. Email me before payment and I'll send modified order details with payment options.

IMPORTANT SAFETY NOTICE :

Some children have needed surgery, or even died, after swallowing two or more small magnetic balls from the magnet toy "Neocube".
As a result, in July 2014, the NZ Government created legislation covering the sale of all Neodymium magnets except those sold singly, and very large ones - which are also dangerous, but for different reasons.

The legislation bans the sale of groups of two or more magnets for use as puzzles/toys/jewellery, construction kits, or "personal" use.
Sales are allowed for hardware purposes, commercial & industrial use, scientific use, use by educational institutions, and use where the magnets are intended to become component parts of other products.

A shame the Neocube was banned, because it was an outstanding and very educational "toy".
Perhaps legislation could better have focussed on requiring warnings for buyers, i.e. treat the product in much the same way as for other dangers to health and life of children, such as paracetamol, swimming pools, bicycles, power points, electric jugs, deflated balloons, button batteries, kids' toys with choking hazards, etc. These items have not been banned. Parent education is what is important.
