Wacker Neuson 5000054147 Screw 5/16-24 X 1-1/4 Hx.Lock

The Wacker Neuson Screw 5/16-24 X 1-1/4 Hx.Lock is a genuine OEM fastener designed for the CT30, CT36, and CT48 series walk-behind concrete power trowels. As a direct OEM replacement, is manufactured to Wacker Neuson's exact specifications, ensuring correct thread engagement and clamping load in every application. This screw fits a wide range of CT-series trowel configurations, including ADT, AGT, ADP, and -E variants across the 30-inch, 36-inch, and 48-inch platform sizes. When it comes to hardware on high-vibration concrete finishing equipment, using the correct OEM fastener keeps critical assemblies secure and torque values accurate.

Key Features

• Genuine OEM Thread Integrity — Manufactured to Wacker Neuson's exact 5/16-24 UNF thread specification, ensuring full thread engagement and consistent clamping force on concrete trowel assemblies.
• Drop-In Hardware Replacement — Matches the original hex lock fastener profile for direct installation with standard tooling — no rethreading or modification to the mounting hardware required.
• Broad CT-Series Compatibility — Fits CT30, CT36, and CT48 walk-behind power trowels across ADT, AGT, ADP, and CE-compliant -E variants, covering both 30-inch and 36-inch blade diameter platforms.
• Vibration-Resistant Locking Design — The hex lock fastener style is engineered to resist loosening under the sustained high-frequency vibration generated during concrete finishing operations, helping maintain structural integrity over time.
• Correct Torque Compliance — Using the specified OEM screw ensures torque values remain within design parameters, which is particularly important on rotating blade and guard assemblies where fastener failure presents a safety risk.

A hex lock screw is a threaded fastener with an integrated locking feature that resists self-loosening caused by vibration and dynamic loads. On walk-behind concrete trowels like the CT30, CT36, and CT48, fasteners of this type are used throughout the machine to secure guards, blade spider assemblies, handles, and other structural components that experience continuous vibration during operation. When a fastener loosens or fails in service, it can allow components to shift out of alignment, create excessive wear on adjoining parts, or — on rotating assemblies — present a hazard to the operator. Replacing worn or missing screws with the correct OEM specification fastener restores the designed clamping force and keeps the assembly performing as intended.
