Multiquip 0042810000 Flat Washer

The Multiquip 0042810000 Flat Washer is a genuine OEM component designed for Multiquip DCA, DIS, and MQP series equipment, including ultra-silent and super-silent generator models. As a direct OEM replacement, it meets the original engineering specifications set by Multiquip for the units it serves. Confirmed fitment includes models such as DCA300SSJU4F3, DCA70USI2, DCA70USI3CAN, DCA45SSIU4, DCA70SSIU2, DIS185SSI4F, DCA300SSJU4F3PD, and MQP56. Sourcing the correct OEM hardware ensures consistent clamping loads and proper assembly integrity across every service interval.

Key Features

• Genuine OEM Hardware Grade — Manufactured to Multiquip's original material and dimensional standards, ensuring correct load distribution for the fastener assemblies used in these generator and compressor platforms.
• Drop-In Replacement — Matches the original bore diameter, outer diameter, and thickness so it seats correctly without any modification to the mating hardware or fastener.
• Broad Series Fitment — Compatible with DCA ultra-silent, DCA super-silent, DIS, and MQP standby generator and air compressor models, covering a wide range of Multiquip portable power equipment.
• Protects Mating Surfaces — Distributes fastener clamping force evenly, preventing surface damage, deformation, or loosening under vibration loads typical of generator and compressor operation.
• Essential Service Stock — A high-use hardware item across multiple assembly points; keeping genuine replacements on hand speeds up routine maintenance and rebuild work.

A flat washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading the clamping force over a wider area, it prevents the fastener from pulling through or damaging softer or thinner materials and helps maintain consistent joint tension over time. In generator and compressor applications where vibration is constant, a correctly sized and properly graded washer is critical to keeping assemblies tight and preventing fastener loosening that could lead to component movement or premature wear.
