198631 - Miller M10-1.5 DIN 980V Lock Nut

Miller 198631 M10-1.5 DIN 980V Lock Nut

The Miller 198631 is a high-specification replacement nut designed to meet the rigorous demands of industrial welding environments. Manufactured to the DIN 980V standard, this component is an all-metal prevailing torque type hexagon nut. Unlike nylon-insert lock nuts, the all-metal design of the DIN 980V allows it to withstand higher temperatures and harsh chemical environments often found in welding workshops, ensuring the fastener retains its locking capability even under thermal stress.

This specific nut features an M10-1.5 metric coarse thread pitch, a common standard in Miller Electric machinery. It is driven by a 17mm hex, allowing for installation with standard metric wrenches and sockets. The "10H" designation indicates the hardness class of the steel, signifying a high-strength fastener capable of handling significant proof loads without stripping or deforming. This makes it critical for securing structural components or internal assemblies within power sources where vibration resistance is paramount.

The nut is finished with a protective plating, typically zinc, to provide resistance against oxidation and corrosion. When maintaining or repairing Miller equipment, using the correct grade and standard of hardware is essential for safety and longevity. The Miller 198631 ensures that the mechanical integrity of your machine is maintained to factory specifications.
