N35 Neodymium Disc Magnet 1/2 × 3/16 in – SKU 8458

SKU 8458 is an N35 neodymium disc magnet measuring 1/2 inch in diameter × 3/16 inch thick. It is axially magnetized through its thickness, placing the north and south poles on the two flat circular faces. This compact, proportionally thick disc suits closures, fixtures, sensors, displays, prototypes, and production assemblies requiring a concentrated magnetic field.

Design notes for this 1/2-inch disc

Confirm pole orientation, air gap, target-steel thickness, adhesive selection, and dimensional stack-up during assembly. Sintered neodymium magnets are hard and brittle, so avoid impact, snap-together collisions, uneven clamping, and excessive mechanical stress.

The listed 7.05 lb pull force is a comparison value under defined contact conditions, not a guaranteed safe working load. Air gaps, surface roughness, coating, thin target steel, and shear loading can reduce usable force.

Use the magnet pull force calculator for preliminary magnet-to-steel screening and compare material options in the neodymium magnet grades chart. Browse our magnet catalog or submit the magnet RFQ builder for volume pricing or a custom requirement.
