Multiquip EM933 Flat Washer SAE 5/8

The Multiquip EM933 is a genuine OEM Flat Washer SAE 5/8 designed for a wide range of Multiquip and Whiteman equipment, including HTX, STX, MD, LD, and PRX series ride-on power trowels, walk-behind trowels, trash pumps, water trailers, light towers, flat saws, and walk-behind rollers. As an authentic Multiquip OEM component, EM933 is manufactured to the same specification as the original hardware installed at the factory, ensuring dimensional accuracy across every application it supports. This washer fits an extensive list of models — from the HTX6H and STX55J6 to the MD80, MD105, LD60, PRX, and beyond — making it a practical stocking item for crews running multiple Multiquip machines. Sourced directly through authorized distribution channels, this is the part number to order when you need confidence in the fit.

Key Features

• Correct SAE 5/8 Dimensioning — Manufactured to SAE flat washer standards, ensuring proper load distribution across the fastener face without over-compressing the mating surface.
• Genuine OEM Component — An authentic Multiquip part produced to the same material and tolerance specs as the hardware originally installed on covered equipment.
• Broad Cross-Equipment Compatibility — A single part number that spans HTX, STX, MD, LD, and PRX ride-on trowels; walk-behind trowel series; trash pumps; water trailers; light towers; flat saws; and walk-behind rollers.
• Maintains Fastener Joint Integrity — A correctly sized flat washer distributes clamping load evenly, preventing fastener pull-through and surface damage that can allow joints to loosen under vibration.
• Drop-In Hardware Replacement — Matches the original hole clearance and outer diameter so it seats without modification in any assembly position where EM933 is specified.

A flat washer serves as a load-spreading interface between a fastener — such as a bolt head or nut — and the surface it clamps against. By distributing clamping force across a wider area, it protects the mating material from deformation and helps the fastener maintain consistent tension, which is especially important on equipment subject to continuous vibration like power trowels and compaction machinery. When a washer is missing, undersized, or worn, the fastener can work loose or pull through softer material, leading to joint failure and potential damage to surrounding components.
