The Multiquip 16515 Jam Nut 1-5/16-16 Right Hand is a genuine OEM fastener designed for WRS5200, WRS5200DFPU, WRSPUDF, and WSHE-A series screed equipment. As a direct OEM replacement, part 16515 is manufactured to the same specifications as the original hardware, ensuring proper thread engagement and secure holding on right-hand threaded assemblies. Sourced directly through Multiquip's authorized parts network, this jam nut is the correct choice when servicing Whiteman ride-on roller screeds and WSHE-A vibratory screed systems. DHS Equipment stocks genuine Multiquip parts so you can get your screed back in service without guesswork.
Key Features
- Right-Hand Thread Specification: — Machined to a 1-5/16-16 right-hand thread standard, matching the original fastener exactly to prevent cross-threading or loosening under vibration.
- Genuine OEM Hardware: — Manufactured to Multiquip's original material and hardness standards, delivering the same clamping force and corrosion resistance as the part it replaces.
- Direct Installation Fit: — Replaces the factory jam nut without reworking mating threads or adjacent components, keeping your screed assembly in correct alignment.
- Broad Screed Compatibility: — Confirmed fitment across WRS5200, WRS5200DFPU, WRSPUDF ride-on roller screeds and WSHE-A series vibratory screeds.
- Vibration-Critical Retention: — Jam nuts on screed assemblies are subject to constant vibration loading; using an undersized or incorrect-grade nut risks loosening, misalignment, and component damage during operation.
A jam nut is a thin locking nut threaded against a primary nut or shoulder to prevent rotation and maintain positional lock under dynamic loads. On roller screeds and vibratory screed assemblies, jam nuts secure adjustment points and drive components that experience constant vibration during concrete finishing operations. When a jam nut wears, strips, or is installed with the wrong thread specification, the assembly can shift out of adjustment mid-pour, leading to uneven screed depth and potential damage to the threaded shaft it contacts. Replacing it with the correct OEM-spec part — Multiquip 16515 — restores proper lock and keeps the screed performing consistently across the full pass.
