Multiquip 90012888000 Flange Bolt 6X40 GX340K1

The Multiquip 90012888000 is a genuine OEM Flange Bolt 6X40 GX340K1 designed for a range of Multiquip walk-behind rollers, arc welders, and gasoline-powered generators including the MRH800GS, V305EH, GAW180HE, GAW180HE1, GAW180HEA, GA6HEB, GA6HB, and GA6HZ. Sourced directly from Multiquip, this fastener matches the original specification so it seats and torques correctly without guesswork. Cross-referencing part number 90012888000 before ordering is the best way to confirm this is the right bolt for your machine.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the exact thread pitch, shank diameter, and flange geometry specified for GX340K1-equipped Multiquip equipment, so clamping load is consistent with the original design.
• Drop-In Installation — Flange bolt head distributes clamping force evenly across the mating surface, seating flush without the need for a separate washer in the original bolt location.
• Broad Fitment Across Multiquip Families — Confirmed fit for MRH800GS and V305EH walk-behind rollers, GAW180HE series arc welders, and GA6H series gasoline generators.
• Structural Integrity Under Vibration — A properly torqued OEM flange bolt maintains joint integrity in high-vibration applications; a worn, stretched, or incorrect bolt risks joint loosening and component misalignment.
• Exact Part Number Match — Ordering by Multiquip part number 90012888000 eliminates substitution risk and ensures the fastener meets the dimensional requirements of the original assembly.

A flange bolt combines a standard hex bolt with an integrated flanged washer head, spreading the clamping load over a wider area to prevent fastener pull-through and reduce the chance of loosening under vibration. In equipment like rollers, arc welders, and generators — all of which operate under sustained mechanical stress — using the correct flange bolt at the specified torque is critical to keeping structural and engine-mounted components properly secured. When a flange bolt becomes stripped, corroded, or under-torqued, it can allow movement between mating parts, leading to accelerated wear, misalignment, or component failure.
