In general, a lockwasher is a washer designed to help resist loosening of a threaded fastener under vibration. It is typically used between a bolt or nut and the surface it clamps, and its exact design and construction must be checked against the catalog listing.
Use part number 0138502 as the reference when ordering, and confirm it matches the fastener size and location you need. The catalog associations for the 826H and 836G carry recorded conditions shown on those entries, so check those conditions against your machine before relying on them.
