Product Description:

This neodymium block magnet measures 40 mm (L) x 10 mm (W) x 4 mm (T).
It has a 4 mm countersunk hole with an 8 mm head width. Countersunk magnets allow the head of a screw, when placed in the hole, to sit flush with or below the surface of the magnet. GRADE N38. Please note: this magnet is susceptible to breaking if over tightened.

About Countersunk Magnetic Blocks:

This countersunk block magnet is ideal for fastening and popular with carpenters, sheet metal fabricators, aluminum and glazing suppliers, and fixture supply outlets. A great, general all-purpose magnet which can be fixed in place with a screw that sits flush with the surface of the magnet.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.
