Multiquip 030212300 Lock Washer

The Multiquip is a genuine OEM Lock Washer designed for a wide range of Multiquip equipment, including MTX and MT series rammers, MVH and MVC series plate compactors, MRH and RW series rollers, and select Multiquip pumps. As an authentic OEM component, is sourced directly through Multiquip's authorized parts network to ensure correct material grade, dimensions, and thread compatibility across every application it covers. Confirmed fitment spans models including MTX70HDR, MTX80HDR, MVH508DE, MVH408GH, MVC88VTHW, MRH800GS, RW1404, and many more — making this one of the most broadly applicable fastener components in the Multiquip parts catalog. Sourcing the correct lock washer matters more than it might seem: an incorrect or worn part can compromise clamping force and lead to fastener loosening under vibration.

Key Features

• Genuine OEM Material Grade — Manufactured to Multiquip's specified hardness and tensile standards, ensuring the washer delivers consistent locking force without deforming under torque.
• Broad Cross-Equipment Compatibility — A single part number covering rammers (MTX, MT), plate compactors (MVH, MVC), walk-behind rollers (MRH, RW), and trash pumps — simplifying parts inventory across a mixed fleet.
• Direct Bolt-In Replacement — Sized to match the original fastener stack exactly, dropping straight into existing hardware assemblies without reworking the joint.
• Vibration-Resistance Where It Counts — On compaction and ramming equipment, joints are subject to continuous high-frequency vibration; a correctly rated lock washer maintains clamp load and prevents critical fasteners from backing out during operation.
• Authorized OEM Sourcing — Supplied through Multiquip's authorized parts distribution network, so the part number, specification, and packaging all match what came off the assembly line.

A lock washer is a hardened fastener component placed beneath a nut or bolt head to resist loosening caused by vibration, dynamic loads, or thermal cycling. On heavy-duty compaction equipment such as rammers and plate compactors — which generate intense, repetitive shock forces during normal operation — fastener joints are especially vulnerable to self-loosening over time. The lock washer works by maintaining tension in the fastener joint, biting into both the mating surface and the fastener to resist rotation. When a lock washer becomes worn, flattened, or is substituted with an incorrect size, clamping force drops and fasteners can work loose, leading to component misalignment, accelerated wear on surrounding hardware, or failure of structural and mechanical joints.
