Key Features

• Genuine OEM Material Spec — Manufactured to the same hardness and surface finish tolerances as the original, ensuring consistent load distribution across fastened joints.
• Broad DCA Series Coverage — Compatible with a wide range of Multiquip DCA Ultra-Silent and Super-Silent generator models, including DCA70SSIU4F, DCA400SSK, DCA600SSV, DCA800SSK2, MQP240, and many others.
• Direct-Fit Replacement — Matches the original bore diameter and outer dimensions, seating correctly against mating hardware without adjustment.
• Protects Fastened Surfaces — Distributes clamping load evenly to prevent fastener pull-through and surface damage on generator enclosure panels and internal assemblies.
• Supports Correct Torque Retention — Proper washer spec helps maintain consistent clamp force over time, reducing the risk of fastener loosening under generator vibration.

A flat washer serves as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it clamps against. By distributing the clamping force over a larger area, it prevents the fastener from pulling through or damaging the material beneath it, and helps maintain consistent torque values across the joint. In generator applications where vibration is continuous during operation, using the correct washer with the right material grade and dimensions is important for keeping assemblies secure and preventing premature fastener loosening or surface wear.
