The Multiquip 2101428 is a genuine OEM 1/4" NC Nut designed for a wide range of Whiteman mixer, Essick mixer, Mayco concrete pump, and roller models. As an authentic Multiquip replacement part, it is manufactured to the exact thread specification and material grade required to maintain proper assembly integrity across compatible equipment. Confirmed fitment includes Whiteman mixer models WM70SLF, WM70PLF, WM90SLF, WM90PLF, WM45HCE, WM70S/P, and WM90S/P, Essick mixer models EM70P/S and EM90P/S, Mayco and LS-series concrete pump models LS300GK, LS300G, LS300P, LS600P, LS60TD, and C30HDGA, and the R2000H static roller. Sourcing the correct OEM nut ensures threads engage fully and fastened assemblies stay secure under the vibration and load cycles these machines generate.
Key Features
- Genuine OEM Thread Specification — Manufactured to the exact 1/4" NC thread form and material grade required by Multiquip, ensuring full thread engagement without cross-threading or fastener fatigue.
- Direct Hardware Replacement — Matches the original fastener profile for straightforward installation wherever this nut is specified in the assembly — no thread chasing or rework needed.
- Broad Cross-Equipment Fitment — Confirmed for Whiteman and Essick mixer models (WM70, WM90, WM45, EM70, EM90 series), Mayco and LS-series concrete pumps (LS300, LS600, C30HDGA), and the R2000H roller.
- Vibration-Resistant Holding Power — A correctly torqued, spec-matched nut maintains clamp load through the sustained vibration and mechanical stress these machines experience during operation. An undersized or worn fastener risks joint loosening and component damage.
- Wide Application Versatility — A single part number covering multiple Multiquip product lines simplifies parts stocking and streamlines service across mixed fleets of mixers, pumps, and rollers.
A 1/4" NC (National Coarse) nut is a standard-thread fastener used throughout equipment assemblies to secure components, brackets, guards, and hardware to matching bolts or threaded studs. Its role is to maintain consistent clamp load and joint integrity — keeping assembled parts from shifting or separating under operational stress. When a nut is damaged, stripped, or loses its thread integrity, the fastened joint becomes unreliable, which can lead to component misalignment, accelerated wear on surrounding hardware, or outright fastener failure during operation. Using the correct OEM-specified nut ensures the thread form, material strength, and dimensional tolerances match the original design intent of the assembly.
