- Structural Load Distribution — Correctly distributes clamping force across fastened surfaces, preventing localized wear, distortion, or fastener failure that can develop when an incorrect or worn washer is used.
- Verified Part Number — The EM628 part number is traceable directly to Multiquip's OEM parts system, eliminating guesswork when ordering for the C30HD.
A special washer is a precision-dimensioned component used to distribute the load of a fastener — such as a bolt or nut — evenly across a surface, preventing damage to mating parts and maintaining correct clamping force in the assembly. In concrete pump applications, where vibration and hydraulic pressure place constant stress on fastened connections, a correctly specified washer is critical to keeping joints secure and components properly aligned. A worn, incorrect, or missing washer can lead to fastener loosening, accelerated wear on surrounding components, or structural failure within the pump assembly.
