Multiquip EM923057 Flat Washer 1/4

The Multiquip EM923057 is a genuine OEM Flat Washer 1/4 designed for a wide range of Multiquip equipment including Whiteman and Essick mixer series, Whiteman power buggies, Mayco and LS-series concrete pumps, and walk-behind rollers. As a factory-sourced component, EM923057 meets the original engineering specifications set for every machine it serves. This washer is confirmed for use across models including WM45HCE, WBH-16, WBH-21EF, LS300GK, LS600, C30HDGA, V304EH, V305EK, AR14H, AR13D, PRO12, and EM12M series equipment. Sourcing the correct OEM hardware ensures consistent clamping load and surface protection at every fastened joint.

Key Features

• Genuine OEM Hardware Grade — Manufactured to the original material and dimensional specification, ensuring correct load distribution across fastened connections on every compatible machine.
• Drop-In Installation — Sized to seat flush against the 1/4-inch fastener assemblies found throughout these machines, requiring no modification to existing hardware configurations.
• Broad Cross-Equipment Fitment — Confirmed for Whiteman mixer and power buggy series, Mayco and LS-series concrete pumps, Essick stationary mixers, and Multiquip walk-behind rollers including WBH-16, WBH-21EF, LS300, LS600, WM45HCE, and V304 and V305 roller models.
• Surface Protection at Contact Points — The washer distributes fastener load over a wider bearing area, preventing surface deformation and protecting mating components from wear at bolted joints during heavy-duty operation.
• Correct Torque Retention — A properly fitted flat washer maintains consistent clamping force under vibration and load cycles, helping fastened assemblies hold their specified torque rather than loosening prematurely in the field.

A flat washer is a simple but essential hardware component placed between a fastener — such as a bolt or nut — and the surface it clamps against. Its primary role is to spread the load of the fastener over a larger area, preventing the fastener head or nut from digging into or deforming softer materials. On equipment that operates under continuous vibration, such as concrete pumps, mixers, and rollers, washers also help maintain consistent clamping force and reduce the risk of fastener loosening over time. Using the correct OEM-specified washer ensures the joint behaves as the original design intended — substituting an incorrect size or grade can compromise fastener torque and lead to premature joint failure.
