Multiquip 90114SA0000 Self-Locking Nut 6mm

The Multiquip 90114SA0000 is a genuine OEM Self-Locking Nut 6mm used across a wide range of Multiquip, Whiteman, Essick, and STOW equipment. As a direct OEM replacement, this fastener is manufactured to the same specification as the original hardware installed at the factory, ensuring a proper, secure fit wherever a 6mm self-locking nut is called for. The 90114SA0000 is confirmed for use on MVC and MVH series plate compactors, WM and MC series mixers, walk-behind trowels, power buggies, saws, pumps, rollers, vibrators, generators, and more.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the same torque retention and thread specification as the original hardware, maintaining the correct clamping force in vibration-intensive applications.
• Self-Locking Thread Design — The prevailing-torque locking feature resists loosening under the vibration and load cycles common to compactors, mixers, trowels, and saws — no additional locking hardware needed.
• Broad Cross-Equipment Compatibility — Fits an extensive range of Multiquip equipment families including MVC and MVH plate compactors, WM and MC series mixers, walk-behind trowels, power buggies, pumps, and flat saws, among others.
• Direct Drop-In Replacement — Matches OEM thread pitch and hex dimensions for a straightforward installation using standard 6mm tooling already on hand.
• Critical for Structural Integrity — Used in fastening covers, guards, frames, and assemblies throughout the machine; a worn or missing self-locking nut can allow components to shift, vibrate loose, or fail prematurely.

A self-locking nut — also called a prevailing-torque nut or nylon-insert nut — is a fastener engineered to resist loosening when subjected to vibration, shock, or cyclical loading. Unlike a standard hex nut, the locking feature creates friction on the thread engagement, keeping the fastener secure without the need for split washers or thread-locking compounds. In heavy construction equipment, where engines, vibrating plates, and rotating assemblies generate constant movement, self-locking fasteners are used in critical joints throughout the machine. When a self-locking nut loses its locking tension — whether through reuse, heat exposure, or wear — it can allow panels, guards, or structural members to work loose, creating both operational and safety concerns. Replacing worn hardware with the correct OEM-spec nut restores the joint's original holding strength.
