Professional Applications & Engineering Value

These N50 grade neodymium magnetic washers solve critical engineering challenges in industrial assembly and mounting applications where conventional 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 additional hardware. The nickel plated finish ensures corrosion resistance in various industrial environments, while the precise 0.28" ID and 0.9" OD dimensions provide perfect compatibility with standard 1/4" screw sizes. These magnetic flat washers are particularly valuable in electronics manufacturing, automotive assemblies, and industrial equipment where temporary but secure positioning is required before permanent fastening. The combination of high magnetic strength and dimensional accuracy makes them ideal for jig and fixture applications, prototype development, and production line setups where quick repositioning and reliable holding power are essential.
