The Wacker Neuson is a genuine OEM Screw 7/16-20 X 1-1/4 Gr5 Z/P designed for CT36 and CT48 walk-behind concrete power trowels and the CRTv36-26A ride-on concrete trowel. As a factory-sourced fastener, meets the exact thread specification, grade rating, and zinc plating standard called out in the original machine design. This screw is confirmed to fit multiple configurations across the CT36-8A, CT36-9, CT48-8A, CT48-9, and CRTv36-26A series, making it a dependable stock item for fleets running these trowel models. Keep a supply on hand to support scheduled maintenance and field repairs without delay.
Key Features
- Grade 5 Tensile Strength — Rated at Grade 5 (Gr5) for the clamping loads found in concrete trowel assemblies, resisting loosening under sustained vibration during operation.
- Zinc-Plated Corrosion Resistance — The Z/P (zinc-plated) finish provides a protective barrier against moisture and concrete slurry exposure common on finishing job sites.
- Correct 7/16-20 Thread Form — Fine-thread 7/16-20 UNF specification ensures full thread engagement with mating hardware exactly as engineered — no chasing threads or re-tapping required.
- Broad CT and CRT Series Fitment — Confirmed for CT36-8A, CT36-9, CT48-8A, CT48-9, and CRTv36-26A trowel configurations, covering a wide range of Wacker Neuson walk-behind and ride-on finishing equipment.
- Genuine OEM Sourcing — Supplied directly from Wacker Neuson as part number 5000164753, matching the original material grade, plating specification, and dimensional tolerances of the fastener installed at the factory.
Fasteners like the Screw 7/16-20 X 1-1/4 Gr5 Z/P serve as critical clamping elements throughout concrete trowel assemblies, securing guards, handles, drive components, and structural panels under the continuous vibration loads that finishing machines generate. A fastener at the correct grade and thread specification distributes clamping force evenly and resists backing out during operation, keeping mating components properly aligned and torqued. When a fastener is substituted with an incorrect grade or thread pitch, joint integrity can be compromised — leading to loosening, component movement, or accelerated wear on surrounding hardware.
