The magnetic flux density differs slightly depending on the measuring device. Please consider them to be only reference values.The adsorptive power is the reference value when the magnet is pulled at a perpendicular angle.

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.
