Uses and applications of magnetic bases with through hole and metric
The magnetic base with through hole and metric is a magnet and container that has a through hole in the centre with the possibility of screwing it into walls and ceilings by means of its metric. They provide high forces and very secure fixings. You can find these bases in applications such as:
Fixing of hooks and other elements
Holding signs, pictures…
Facilities in workshops and offices
If you do not need the metric, you can use countersunk magnets or neodymium magnetic rings. They are flat and circular magnets with a hole in the centre of the magnet made of neodymium that provide high coercivity and high remanence. Φ38mm NdFeB Magnetic Base with Hole for Holding Mounting
The following screws fit into the product, for example:
Hexagon socket head cap screw: ISO 4762 M6 (6 mm)
Hexalobular head cap screw: ISO 14580 M6 (6 mm)
Cross recessed cheese-head screw (Form Z): ISO 7048 M6 (6 mm)
The magnetic base with hole and metric are magnets made of Neodymium, a material that is part of the rare earth, the latest generation of magnetic materials and is composed of an alloy of neodymium, iron and boron that provides great holding power for their applications. These magnetic bases can be used in temperatures up to 80ºC.
The magnetic base is a magnet in the form of a magnetic disk incorporating a through hole in its centre and a metric.
They are very similar to the countersunk magnets but the difference between the magnetic base with hole and metric and the countersunk magnets, is that the former has a metric to screw and fix the object in question better.
