602213 - Miller 602213 Split Lock Washer 3/8-Inch Steel Plated (5-Pack)

Reliable Fastening with Miller 602213 Lock Washers

The Miller 602213 Lock Washer is a critical hardware component designed to ensure the structural integrity and reliability of your industrial equipment. Sold in a convenient package of five, these split lock washers are engineered to prevent fasteners from loosening due to vibration, a common challenge in heavy-duty welding and fabrication environments. By exerting a continuous spring force between the fastener head and the substrate, the washer maintains friction and keeps the assembly tight over time.

Precision Dimensions and Material

Manufactured to exact specifications, this washer features an inner diameter (ID) of 0.380 inches, making it suitable for standard 3/8-inch bolts and studs. The outer diameter (OD) measures 0.691 inches, providing ample surface area for load distribution without interfering with adjacent components. With a thickness of 0.115 inches, the washer is robust enough to handle significant torque requirements without deforming permanently. The construction utilizes high-quality steel that has been plated to offer resistance against rust and corrosion, ensuring longevity even in shop environments where humidity and temperature fluctuations occur.

Industrial Applications

While specifically listed as a replacement part for Miller Electric welding machines, the utility of the 602213 lock washer extends to various mechanical assemblies requiring a 3/8-inch split washer. The split, or helical, design is one of the most effective and widely used methods for locking threaded fasteners. As the bolt is tightened, the split ends of the washer dig into the mating surfaces, creating a physical barrier to rotation while the spring tension compensates for any minor settling of materials. This makes it an essential item for maintenance, repair, and operations (MRO) inventories.

Genuine OEM Quality

Using genuine Miller parts like the 602213 ensures that your equipment remains within factory specifications. Generic hardware may not always meet the precise metallurgical or dimensional standards required for high-performance welding power sources and wire feeders. By choosing this OEM 5-pack, you secure the peace of mind that comes with using components validated by the manufacturer for their specific machinery.
