The Multiquip 0041218000 Flat Washer is a genuine OEM component designed for DCA ultra-silent and MQP standby generator series equipment. Sourced directly through Multiquip's authorized parts network, this flat washer meets the original design specification for the generator models it serves. It is confirmed for use across a wide range of DCA and MQP series machines, including DCA220SSK, DCA300SSC, DCA300SSCU, DCA400SSK, DCA250SSI, DCA500SSK, DCA600SSK, DCA800SSK, and MQP240, among others. When you need a straightforward hardware replacement that installs correctly the first time, the part is the part to order.

Key Features

• Genuine OEM Hardness and Dimensional Accuracy — Manufactured to the original material and dimensional specification, ensuring correct load distribution across fastened joints in generator assemblies.
• Drop-In Hardware Replacement — Matches the original bore diameter, outer diameter, and thickness for direct installation without modification to existing fasteners or mounting points.
• Broad DCA and MQP Series Coverage — Confirmed fitment across DCA220SSK, DCA300SSC, DCA400SSK, DCA400SSK2, DCA250SSI, DCA500SSK, DCA600SSK, DCA800SSK, MQP240, and additional DCA300 and DCA400 variants.
• Proper Clamping Force Distribution — A correctly spec'd flat washer prevents fastener pull-through and surface damage, maintaining structural integrity across generator frame and enclosure connections.
• Supports Long-Term Fastener Integrity — Using the OEM-specified washer prevents uneven stress on bolted connections that can lead to loosening under vibration typical of generator operation.

A flat washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps. In generator assemblies, where vibration is constant during operation, washers prevent fastener heads from embedding into or damaging mounting surfaces and help maintain consistent clamping force over time. When a washer is worn, deformed, or missing, fasteners can loosen progressively, leading to rattling components, misalignment, or structural failure at critical connection points within the generator enclosure or frame.
