Miller 214860 PG21 Nickel Plated Brass Lock Nut

Technical Specifications and Application

The Miller 214860 is a precision-engineered lock nut designed for specific fastening applications within Miller welding systems. This component is characterized by its PG21 thread, a Panzergewinde standard often found in electrical conduit and cable gland fittings. The nut features a 1.26-inch hex width across flats, allowing for tightening with standard industrial wrenches, and has a very low profile with a height of just 0.14 inches, making it suitable for assemblies with limited clearance.

Material composition is a key feature of this component. Manufactured from nickel-plated brass, the nut combines the strength and machinability of brass with the protective properties of nickel. This plating offers excellent resistance to tarnish, wear, and corrosion, which is particularly important in welding environments where equipment may be exposed to humidity, fumes, or varying temperatures. Furthermore, the brass core ensures good electrical conductivity, which is essential if the nut is part of a grounding path or EMI shielding assembly.

This part is supplied as a single unit (Package of 1). It is crucial for technicians and MRO professionals to use the correct thread pitch and diameter when replacing hardware on welding power sources to avoid stripping threads on mating components. The Miller 214860 ensures that your cable management systems or panel mounts remain secure under the vibration and stress of daily welding operations.
