Professional Applications & Engineering Value

These N50 neodymium magnetic washers solve critical retention challenges in industrial assembly and manufacturing. The rare earth magnet construction provides substantially stronger holding force than conventional magnetic washers, making them ideal for securing components in electronics, automotive, and machinery applications where vibration or movement could cause displacement. The through-thickness magnetization ensures uniform magnetic field distribution, while the nickel-plated finish protects against corrosion in harsh environments. Engineered with precise 0.154" ID for No. 6 screws, these washers integrate seamlessly into existing fastener systems, providing reliable magnetic retention without requiring design modifications. The combination of high magnetic strength and thermal stability up to 140°F makes them suitable for applications ranging from sensor mounting to temporary fixturing in production lines.
