The Multiquip EM968354 Lock Washer 5/16 is a genuine OEM component designed for the C30HD concrete pump. As an OEM part, EM968354 is manufactured to the exact specifications required by the machine, ensuring a correct, secure fit without the guesswork of sourcing a generic substitute. This lock washer is a direct match for C30HD applications, giving you confidence that the part you're installing is the right one for the job.
Key Features
- Genuine OEM Specification: — Hardened to the correct tension and torque rating for this fastening application, so the washer grips and holds as intended under operational load.
- Exact 5/16 Sizing: — Matches the fastener diameter used in C30HD assembly points, dropping in without any modification to existing hardware.
- Confirmed C30HD Fitment: — Sourced directly from Multiquip's OEM parts catalog for the C30HD cycloidal-drive concrete pump.
- Prevents Fastener Loosening: — Lock washers are critical in high-vibration environments; the correct hardness and bite angle keep bolted connections from backing out during pump operation.
A lock washer is a small but essential fastening component that sits beneath a nut or bolt head to prevent the fastener from loosening due to vibration, torque, or cyclic loading. In concrete pump applications like the C30HD, where the machine generates significant mechanical vibration during operation, maintaining tight, secure fastener connections is critical to safe and consistent performance. A worn, deformed, or incorrect lock washer can allow fasteners to back out over time, leading to loose assemblies, misalignment, or component failure.
