The Multiquip 1720891040 Flange Bolt D722B is a genuine OEM fastener designed for the DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder series. As a direct OEM replacement, this bolt is sourced from Multiquip's authorized parts supply chain, ensuring it meets the original engineering specifications for this application. Confirm your model code against the fitment list before ordering to ensure a correct match for your DLW400ES series machine.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the same torque and clamping specifications as the original bolt, maintaining proper flange seating and joint integrity on the D722B engine assembly.
- Direct-Fit Replacement — Threaded to the exact pitch and length of the factory bolt, allowing installation without modification to existing mounting surfaces or flanges.
- DLW400ES Series Compatibility — Confirmed fitment for DLW400ES, DLW400ESA, and DLW400ESA1 diesel light welder models.
- Structural Reliability Under Load — Flange bolts distribute clamping force evenly across the mating surface, which is critical for preventing loosening under the vibration and thermal cycling typical of continuous welding operations.
- Correct Part, First Time — Using the OEM-specified 1720891040 eliminates the risk of mismatched thread engagement or under-rated fasteners that can lead to fastener failure or component damage.
A flange bolt serves as a fastening component that combines a standard bolt with an integrated flange, acting like a built-in washer to spread clamping load across a wider surface area. In engine and drivetrain applications such as the D722B engine used in DLW400ES series welders, flange bolts are commonly used where vibration resistance and secure joint retention are critical. A missing, stripped, or incorrect bolt in these locations can result in loose components, fluid leaks, or structural failure of the fastened assembly.
