Magnetic Product Description:

This rare earth block magnet has a length of 40mm, a width of 10mm and a thickness of 4mm. It has the AMF magnet part number 22008. It has a centred 4mm countersunk hole with an 8mm head width.

Please note: this magnet is susceptible to breaking if attachment screws are over-tightened.

Uses for our rare earth block magnets:

When an individual magnet’s pull force limit has been exceeded, the magnetic bond ceases. This characteristic allows designers and tradespeople to choose a magnet as much for its release threshold as for its holding ability.

Magnetic bond and the force needed to cause disengagement could be described as intuitive. A magnets’ release threshold allows designers to fashion products that are much easier to replace, clean and service. This increases a product or devices utility and longevity.

The fastening relationship between magnets and all the various types of modern plastic fabrications and materials has really crowned magnetic bond as the superior adhesion method for the modern world. Outdated fasteners that are penetrative and overengineered, cannot compete with the simple, intuitive and invisible bond that magnets have to offer. The arrival of modern Rare Earth magnets heralded a new era for designers and have been the perfect marriage for plastics ever since.

This Countersunk Neodymium magnet allows for application to projects where the magnet needs to be fixed to a wooden or other types of surface neatly and with no protruding parts above the surface of the magnet. Often applied to sliding doors or cabinets in combination with a metal plate to act as a simple locking device. A self-tapping screw with a slotted or Phillips head will secure the magnet in place.

This countersunk block magnet is ideal for fastening and popular with carpenters, sheet metal fabricators, aluminium and glazing suppliers and fastener supply outlets.

Close the door

Had recently acquired a 1.8m metal cupboard from my neighbor. It had no locking / closing mechanism and so the doors would keep swinging open. The Neodymium Block - 40mm x 10mm x 4mm (Countersunk 4-8mm) worked a treat in keeping them closed.

A quick and easy way to improve the magnetic door seals on refrigerators

The refrigerator door was often left partly open. This was usually caused by something in the refrigerator leaning against the door.

On one refrigerator I simply placed one of these strong magnets behind the plastic door seal. On another I cut the door seal, removed a piece of the plastic door seal magnet and replaced it with one of these strong magnets. These refrigerator doors don't get left partially open any more.
