The Multiquip EM492586 Nylock Nut 5/8 is a genuine OEM fastener designed for a wide range of Multiquip equipment including C30HDGA and LS60TD concrete pumps, MC94 and MC64 series concrete mixers, and WBH-16 and WBH-21 series power buggies. As a direct OEM replacement, this nut is manufactured to the exact specification used in original production, ensuring a correct fit every time. Sourced direct from Multiquip, the EM492586 is the authorized part for any repair or maintenance requiring this specific fastener across compatible models.
Key Features
- Nylon-Insert Locking Security — The nylon collar grips the thread and resists loosening under vibration and dynamic load — critical on high-cycle machines like power buggies and mixer drums.
- Genuine OEM Specification — Manufactured to the exact thread pitch, hardness grade, and dimensional tolerances used in original Multiquip production builds.
- Broad Cross-Model Fitment — A single genuine OEM part number covering C30HDGA, LS60TD, MC94, MC64, WBH-16, and WBH-21 series equipment.
- Correct Clamping Load — Properly torqued to OEM spec, this nut maintains correct clamping force on structural and drivetrain connections — preventing joint loosening that can lead to component misalignment or damage.
- Drop-In Hardware Replacement — Matches the original hex dimensions and thread engagement depth, allowing installation with standard tooling.
A nylock nut — short for nylon-insert locking nut — is a standard hex nut fitted with a nylon collar at the top of the thread. As the bolt passes through, the nylon deforms slightly around the threads, creating resistance that keeps the nut from backing off under vibration or repeated loading cycles. On equipment like power buggies, concrete mixers, and concrete pumps, where constant movement and engine vibration are present, fastener security is essential. A worn or missing locking insert allows fasteners to work loose over time, which can result in structural play, accelerated wear on surrounding components, or outright mechanical failure if left unchecked.
