Multiquip 933242 Flat SAE 3/8 Washer

The Multiquip 933242 is a genuine OEM Flat SAE 3/8 Washer designed for a broad range of Multiquip and Whiteman equipment, including SP, PS, and CS series pavement saws, the MQ62TK trash pump, and walk-behind and ride-on power trowel models. As a genuine OEM component, it is manufactured to meet the same dimensional and material standards as the original hardware used on the production line. Confirmed fitment spans models including SP303516, SP403016, SP706016, PS403016, PS706016, CS403016, MQ62TK, MD105, LD6, CA4HC, CA4HM, HDA-SERIES, and many additional SP, PS, and CS variants. Keeping the correct hardware on hand ensures fastened assemblies stay torqued and secure throughout demanding cut cycles and pour schedules.

Key Features

• SAE 3/8 Dimensional Accuracy — Meets SAE flat washer standards for correct load distribution across fastener contact surfaces, preventing pull-through and surface damage on mating components.
• Genuine OEM Part — Sourced directly from Multiquip, this washer carries the same material grade and thickness specification as the hardware originally installed at the factory.
• Wide Cross-Equipment Fitment — Compatible across SP, PS, and CS series pavement saws, MQ62TK trash pump, and multiple walk-behind and ride-on trowel families including MD105, LD6, CA4HC, CA4HM, and HDA-Series.
• Direct Drop-In Installation — Standard SAE 3/8 sizing installs with no modification to existing fastener hardware or mounting points on any compatible model.
• Structural Integrity Under Vibration — On high-vibration equipment like pavement saws and compaction machines, a correctly sized washer distributes clamp load evenly and resists loosening over time; an undersized or worn washer allows joint movement and accelerated fastener fatigue.

A flat washer serves as a load-spreading interface between a fastener head or nut and the surface being clamped. By distributing the clamping force across a wider area, it protects softer or thinner materials from deformation and helps maintain consistent clamp load in bolted joints. On equipment subject to sustained vibration — such as pavement saws and power trowels — using the correct SAE-rated washer is essential; an incorrect size or a worn, deformed washer reduces joint preload and can allow critical assemblies to work loose during operation.
