The Multiquip 030204100 Spring Washer M4 is a genuine OEM component designed for MRH800GS walk-behind rollers and FHA-50/60 and FXA-50A/60A concrete vibrators. Sourced directly from Multiquip, this small but critical fastener hardware piece ensures correct clamping force and vibration resistance across its compatible equipment families. Verified fitment covers the MRH800GS roller series alongside the FHA-50, FHA-60, FXA-50A, and FXA-60A vibrator models. When replacing worn or damaged hardware, using the correct OEM specification washer keeps assemblies torqued to proper values and prevents fastener loosening under sustained operation.
Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to Multiquip's exact spring rating for M4 fastener assemblies, maintaining correct clamping load under vibration and repeated use.
- Direct-Fit M4 Hardware — Sized to drop into existing M4 fastener positions on compatible machines with no reworking of mounting points required.
- Broad Fitment Across Two Equipment Families — Compatible with MRH800GS walk-behind rollers and FHA-50/60 and FXA-50A/60A concrete vibrators, making it a practical stock item for mixed fleets.
- Vibration-Resistant Fastening — The spring washer design counters the constant vibration inherent in compaction and concrete vibration equipment, preventing fastener back-out during operation.
- Correct Hardware for Torque-Critical Connections — Using the properly rated spring washer ensures bolted connections stay within spec, protecting surrounding components from movement-related wear.
A spring washer works by applying a consistent, controlled load against a fastener head or nut, using its compressed spring action to resist loosening caused by vibration, thermal cycling, or dynamic loads. In equipment like walk-behind rollers and concrete vibrators — where sustained vibration is central to the machine's function — standard flat washers can allow fasteners to gradually back out, leading to loose assemblies, component misalignment, or accelerated wear on adjacent parts. A worn or missing spring washer compromises joint integrity and can cause failures that extend well beyond the fastener itself, making routine inspection and timely replacement of this part an important part of equipment maintenance.
