Professional Applications & Engineering Value

These N50 neodymium magnetic washers solve critical engineering challenges in precision assembly and industrial automation where traditional fastening methods fall short. The rare earth magnet composition combined with through-thickness magnetization creates a powerful magnetic field that securely holds components in place without mechanical fasteners, ideal for temporary fixturing, jig applications, and magnetic mounting systems. The nickel-plated finish ensures corrosion resistance while maintaining the washer's magnetic properties in environments up to 140°F. Engineered specifically for No. 8 screws with precise 0.188" ID and 0.438" OD dimensions, these flat magnetic washers provide reliable performance in electronics manufacturing, automotive assemblies, and industrial equipment where space constraints demand compact yet powerful magnetic solutions.
