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

Maintain Your Equipment with Genuine Miller Hardware

Keep your Miller welding machines running smoothly with the Miller 602213 Lock Washer. This genuine OEM replacement part is essential for securing internal and external components against the rigors of daily operation. Welding power sources, wire feeders, and running gear are subject to constant vibration and thermal expansion cycles. Over time, these forces can cause standard nuts and bolts to back out, leading to loose connections, rattling noises, or even mechanical failure. The 602213 split lock washer is the factory-correct solution to maintain tight, secure assemblies.

Technical Specifications

This pack contains five (5) steel plated lock washers. Each washer is precision-engineered with a 0.380-inch inner diameter, designed to fit 3/8-inch nominal fasteners perfectly. The outer diameter is 0.691 inches, and the thickness is a substantial 0.115 inches. The "split" or helical spring design is the key to its function; it acts as a spring under the fastener head, absorbing shock and maintaining tension on the bolt assembly. The plated finish provides a layer of protection against oxidation, which is vital for maintaining the ease of future maintenance and preventing seized or rusted hardware.

Why Choose OEM Parts?

When repairing or maintaining expensive welding equipment, every component matters. The Miller 602213 is not just a generic hardware store washer; it is sourced to meet Miller's specific quality control standards. Using the correct washer ensures that the clamping force is applied correctly, protecting delicate components from damage due to over-tightening or loose parts. Whether you are replacing a worn-out part during a scheduled service or assembling a new accessory, this 5-pack ensures you have the right hardware on hand.

Installation and Usage

Installation is straightforward: simply place the lock washer between the nut (or bolt head) and the flat surface or flat washer. Ensure the fastener is torqued to the recommended specification for the grade of bolt being used. The split ends of the washer will compress flat, exerting the necessary locking force. This pack of five is ideal for keeping in your shop's spare parts bin, ensuring you are never halted by a missing piece of hardware during a critical repair.
