Key Features

• Genuine OEM Hardware Integrity — Manufactured to original Multiquip specifications, delivering the correct spring tension and bite angle required for secure fastener retention in generator assemblies.
• Drop-In Replacement — Matches the original 0042512000 lock washer in bore diameter, outer diameter, and thickness for direct installation without reworking mating fasteners.
• Broad DCA Series Coverage — Fits a wide range of DCA super-silent and ultra-silent generator models including DCA220, DCA300, DCA400, DCA600, DCA800, and DCA1100 variants.
• Vibration Resistance — Designed to maintain clamp load under the continuous vibration inherent to generator operation, preventing fastener loosening that could compromise structural or electrical connections.
• Correct Material Grade — Sourced as OEM hardware to ensure the appropriate hardness and corrosion resistance for long-term use in demanding generator environments.

A lock washer is a small but critical fastening component that prevents nuts and bolts from backing out under vibration and dynamic load. In generator applications, where constant engine vibration is transmitted throughout the frame and enclosure, even minor fastener loosening can lead to structural movement, misalignment, or compromised electrical connections. A worn, deformed, or missing lock washer allows fasteners to lose clamping force over time, which can escalate into more significant mechanical or electrical faults if left unaddressed.
