Multiquip EM492574 Hex Nut 3/8" NF G5

The Multiquip EM492574 is a genuine OEM Hex Nut 3/8" NF G5 designed for a wide range of Multiquip equipment including Essick mixer models EM90P/S and EM70P/S, Whiteman mixer models WM70S/P and WM90S/P, and Whiteman hydraulic power buggy models WBH-16, WBH-16E, WBH-16F, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH21EPA, WBH-21EFP, and related variants. As a genuine OEM part, EM492574 is manufactured to the exact grade and thread specification required by the original design, ensuring a proper and secure fastening connection. DHS Equipment supplies this part direct, so you can verify fitment by model code and order with confidence.

Key Features

• Grade 5 Fastener Integrity — G5 classification means this nut meets the tensile and proof-load requirements needed for structural and mechanical fastening on heavy-use equipment.
• Correct Thread Specification — 3/8" NF (National Fine) thread form matches the exact pitch of the mating hardware on these machines, ensuring full thread engagement without cross-threading risk.
• Genuine OEM Part — Sourced directly from Multiquip as an OEM component, EM492574 is the same hardware used in original assembly — not an approximation.
• Broad Multiquip Fitment — Confirmed for Essick mixers (EM70P/S, EM90P/S), Whiteman mixers (WM70S/P, WM90S/P), and Whiteman hydraulic power buggies across the WBH-16 and WBH-21 series.
• Critical Retention Role — A correctly spec'd nut at this grade prevents fastener fatigue, joint loosening, and hardware failure under the vibration and load cycles typical of mixer and buggy operation.

A hex nut is a threaded fastener used to clamp and retain components in place by threading onto a corresponding bolt or stud. On equipment like concrete mixers and power buggies, fasteners are subjected to constant vibration, torque, and mechanical stress — making the correct grade and thread specification essential. A nut that is underspec'd in grade or mismatched in thread pitch can back off under load, strip its threads, or allow connected components to shift, leading to premature wear or mechanical failure at the joint.
