9715 – N48 Countersunk Ring Magnet 1/4″ OD x 0.096″ ID x 0.275″

SKU 9715 is an N48 countersunk neodymium ring magnet measuring 0.250 in OD × 0.096 in ID × 0.275 in thick. Axially magnetized and nickel plated, it gives engineers, OEMs, and procurement teams a compact mechanically mountable ring for fixtures, closures, sensors, positioning features, and embedded assemblies.

Mounting and ring-design notes

Keep the fastener head within the countersunk profile so the magnet can seat consistently against the mounting surface. Because sintered neodymium is brittle, avoid over-tightening the fastener or introducing bending loads around the countersunk area.

The listed pull force is a reference value under defined conditions. Fastener seating, air gap, target-steel thickness, contact area, surface finish, temperature, and load direction all affect actual performance. Use the Magnet Pull Force Calculator for preliminary screening and review What Is a True Radial Magnet? when comparing ring magnetization styles.
