The Multiquip EM26353 Jam Nut Left Hand 1-14 is a genuine OEM fastener designed for WSHE-A Series vibratory screeds. As a factory-sourced component, EM26353 is manufactured to the same specifications as the original hardware, ensuring correct thread engagement and secure locking without risk of cross-threading or loosening under vibration. This part is confirmed for WSHE-A Series truss screed equipment and ships as a direct replacement for the original jam nut position on these machines.
Key Features
- Left-Hand Thread Integrity — Purpose-machined with a left-hand 1-14 thread profile, preventing accidental loosening in applications where rotation would back off a standard right-hand fastener.
- Genuine OEM Construction — Sourced directly from Multiquip, this jam nut meets the same material hardness and thread tolerance specifications as the original production hardware.
- Direct-Fit for WSHE-A Series Screeds — Engineered specifically for WSHE-A Series vibratory truss screeds, this nut installs in the correct position without modification to the mounting assembly.
- Vibration-Resistant Locking — The jam nut design provides a secondary locking layer against an adjoining nut or shoulder, maintaining consistent clamping force even under sustained eccentric shaft vibration.
- Protects Screed Alignment — A loose or incorrect jam nut can allow critical screed components to shift during operation, compromising surface levelness and finish quality; replacing a worn unit restores proper adjustment holding.
A jam nut is a thin, secondary nut threaded onto a fastener or shaft and tightened against a primary nut or surface to lock the assembly in place. On vibratory screed equipment like the WSHE-A Series, jam nuts are used to secure adjustment points that are subject to constant vibration — without them, those adjustments can drift during operation, leading to uneven concrete finishing and potential component wear. Replacing a worn or damaged jam nut promptly keeps the screed's geometry stable and its output consistent across the full width of the truss.
