The Multiquip 0278350100 Flange Nut is a genuine OEM fastener designed for DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, DAC7000SSA, and DLW300ES series equipment. As a direct OEM replacement, this flange nut is manufactured to the same specifications as the original hardware, ensuring a proper seating fit without modification to surrounding components. Sourced directly through Multiquip's authorized parts program, 0278350100 is the correct replacement for keeping diesel generators and welder units properly fastened and structurally sound.
Key Features
- Genuine OEM Fastener Grade — Manufactured to the same hardness, thread pitch, and flange bearing surface spec as the original, so clamping load is maintained correctly across the joint.
- Integrated Flange Design — The built-in washer flange distributes clamping force evenly across the mating surface, eliminating the need for a separate flat washer and reducing the chance of fastener loosening under vibration.
- Broad Series Fitment — Confirmed fit for DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, DAC7000SSA, and DLW300ES series diesel generators and welders.
- Vibration Resistance — Generator and welder equipment operates under sustained vibration loads; a correctly torqued flange nut maintains joint integrity and prevents component shift or loosening over extended run time.
- Exact OEM Part Number — Ordering by Multiquip part number 0278350100 ensures you receive the correct thread size, material grade, and flange diameter for your specific machine configuration.
A flange nut is a standard hex nut with an integrated circular flange on one end that acts as a built-in washer. This flange spreads the clamping load over a larger surface area, which is especially important on equipment subject to continuous vibration — such as diesel generators and engine-driven welders — where conventional nuts can gradually back off and compromise structural or mechanical connections. When a flange nut wears, strips, or goes missing, the joint it secures can shift or loosen, leading to component misalignment, excessive vibration, or potential mechanical failure at that assembly point.
