The Multiquip 938067 Top Lock Nut 3/4-10 GR9 YZ is a genuine OEM fastener designed for Multiquip flat saw and pavement saw models including the SP4, SP605716, SP605720, SP605726, SP605730, SP605736, and SP6457 series. As a Grade 9 yellow zinc-coated top lock nut, this hardware is engineered to maintain secure clamping force under the high-vibration operating conditions common to pavement and flat saw applications. Sourced directly from Multiquip, part 938067 ensures a direct OEM replacement that matches the original fastener specification. Verify your model against the fitment list above before ordering to confirm compatibility.
Key Features
- Grade 9 Clamping Strength — GR9-rated construction delivers higher tensile and proof load ratings than standard hardware, holding firmly where lesser fasteners can loosen under load.
- Yellow Zinc Coating for Corrosion Resistance — YZ finish provides a protective barrier against moisture and oxidation, extending service life in outdoor cutting environments.
- Top Lock Design for Vibration Resistance — The prevailing-torque locking feature resists self-loosening caused by the continuous vibration generated during pavement and flat saw operation.
- Direct OEM Replacement — Matches the original 3/4-10 thread specification exactly, threading onto existing hardware without rework or modification to the saw assembly.
- Broad Fitment Across SP Series Saws — Compatible with SP4, SP605716, SP605720, SP605726, SP605730, SP605736, and SP6457 Multiquip flat saw and pavement saw models.
A top lock nut is a prevailing-torque fastener that uses a deformed or friction-generating locking feature at the top of the nut to resist rotation and maintain clamping force without relying solely on thread friction. On pavement saws and flat saws, where blade assemblies and structural hardware are subjected to sustained vibration and impact loads, a loosened nut can compromise blade alignment, create unsafe operating conditions, or lead to accelerated wear on surrounding components. Replacing a worn or damaged top lock nut with the correct OEM-specified fastener restores the designed clamping integrity and keeps critical saw assemblies secured during operation.
