Multiquip 90015883000 Flange Bolt 6X28

The Multiquip 90015883000 is a genuine OEM Flange Bolt 6X28 designed for a wide range of Multiquip, Whiteman, Essick, and STOW equipment across multiple product families. This fastener is a direct OEM replacement sourced to match the original hardware used in production, covering concrete mixers, walk-behind trowels, plate compactors, portable generators, welders, pumps, rollers, masonry saws, flat saws, power buggies, and more. Confirmed fitment spans models including EM-90S, EM-90P, BH11C, BH90C, WPB16, GA-6H, GAW135H, MC-64S, MVC-64H, MVH-200GH, JH90C, and dozens of additional compatible units across the Multiquip equipment portfolio. Replacing worn or missing fasteners with the correct OEM specification hardware ensures structural integrity and keeps assemblies properly torqued and secured during operation.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the exact thread pitch, head geometry, and flange diameter specified for the original assembly, ensuring proper clamping force without over- or under-torque risk.
• Direct Drop-In Installation — Matches the original bolt profile so it seats cleanly into existing threaded bores and flanged surfaces with no reworking of hardware or mounting points.
• Broad Cross-Equipment Compatibility — A single part number covering mixers, trowels, compactors, generators, pumps, saws, rollers, and buggies across Multiquip, Whiteman, Essick, and STOW product lines — ideal for stocking as a common service item.
• Flange-Integrated Bearing Surface — The built-in flange distributes clamping load evenly across the mating surface, reducing the risk of surface damage or fastener loosening under vibration-heavy operating conditions.
• Structural and Operational Safety Relevance — Correct fastener specification is critical on rotating assemblies, engine mounts, and housing covers; using the properly rated OEM bolt maintains the clamping integrity the machine was designed around.

A flange bolt combines a standard hex-head bolt with an integrated washer-like flange beneath the head, which spreads the clamping load over a wider surface area than a plain bolt. This design is commonly used on vibrating equipment — such as compactors, mixers, and trowels — because the flange helps resist loosening under sustained vibration without requiring a separate washer. When a flange bolt is missing, damaged, or replaced with an incorrect fastener, the clamping force on the joint is compromised, which can lead to housing movement, seal failure, or component separation during use. Using the correct Multiquip 90015883000 with the right thread size and flange diameter keeps each assembly properly secured and operating as intended.
