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.1N + S = AdsorptionNo.2N + Fe = AdsorptionNo.3N + N = RepulsionPrecautionsMagnets can potentially be damaged by strong loads. - Screw standard ISO / JIS
