Multiquip 90005ZM3000 Flange Bolt 5X18 GX22 GX31SA DSGPU

The Multiquip 90005ZM3000 is a genuine OEM Flange Bolt 5X18 GX22 GX31SA DSGPU designed for Multiquip gasoline-powered generators and arc welder models including GA6HB, GA6HEB, GAW180HE, GAW180HEA, GAW180HE1, and GA3.6HR. As a direct OEM component, this bolt is manufactured to the exact material grade and dimensional specification required by the engine and frame assemblies it secures. Sourcing the correct fastener ensures proper clamping load and thread engagement — critical factors on vibration-prone equipment like generators and welders. DHS Equipment stocks this Multiquip part ready to ship so your machine gets back to work fast.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the precise tensile strength and thread specification required for engine and drivetrain mounting applications on Multiquip power equipment.
• Integrated Flange Design — The built-in flange distributes clamping load evenly without a separate washer, seating flush against mating surfaces for consistent torque retention.
• Broad Generator and Welder Fitment — Confirmed fit for GA6HB, GA6HEB, GAW180HE, GAW180HEA, GAW180HE1, and GA3.6HR models; verify your model code before ordering.
• Vibration Resistance — Flange bolt geometry resists backing out under the continuous vibration loads typical of generator and welder operation, maintaining structural integrity over long run times.
• Direct OEM Replacement — Part number 90005ZM3000 matches the original Multiquip specification exactly, dropping in without modification to existing hole patterns or hardware configurations.

A flange bolt combines a standard hex bolt with an integrated washer-style flange at the base of the head. This design spreads clamping force across a wider bearing surface, reducing the risk of loosening caused by engine vibration or thermal cycling. On generators and arc welders, where fastener integrity directly affects structural alignment and safe operation, using the correct OEM bolt — rather than a generic substitute with an unverified grade or thread pitch — helps ensure the assembly stays properly torqued through demanding work cycles. A missing or incorrect bolt in these applications can lead to misalignment, component damage, or unsafe machine conditions.
