Key Features
- Grade 8 Strength Rating — Manufactured to Grade 8 tensile standards, delivering the clamping force and shear resistance required in high-vibration screed applications.
- Yellow Zinc Corrosion Protection — The yellow zinc finish provides a corrosion-resistant barrier suited to outdoor concrete finishing environments where moisture exposure is common.
- Exact 1-5/8-12 Thread Specification — Machined to a 1-5/8-12 thread pitch, this nut seats and torques correctly without reworking mating threads or fastener positions.
- Genuine OEM Part — Supplied as an authorized Multiquip OEM component, ensuring material grade and dimensional accuracy match the original hardware specification.
- Fits WRS5200 and WRSPUDF Series Roller Screeds — Confirmed fitment for WRS5200DFPU, WRS5200, and WRSPUDF ride-on roller screed models.
A hex nut of this grade and thread specification is used to secure structural and mechanical connections on ride-on roller screeds, where sustained vibration and load transfer demand fasteners that hold torque without loosening or fatiguing over time. The yellow zinc coating protects the fastener from surface corrosion, extending service life in wet concrete environments. When a fastener of this type is under-spec'd, stripped, or corroded, it can compromise the integrity of the joint it secures, leading to misalignment, excessive wear on mating components, or unsafe operation of the machine.
