Neodymium magnets Disc Counterboreds

Product image
Usage

A countersink or a counterbored hole is provided on the magnet for securing the magnet with a screw on a prescribed location. The inner bore is a straight hole is not threaded. The standard side of the screw installation surface is the N pole. Please select the S pole depending on the usage.

No.1
N + S = Adsorption
No.2
N + Fe = Adsorption
No.3
N + N = Repulsion
Precautions
Magnets can potentially be damaged by strong loads.
Screw standard ISO / JIS
Shapes of screws may vary in size depending on the manufacturer or standard. The shape of the hole has been machined for ISO / JIS standard screws.
