Wacker Neuson 5000150129 Screw 3/8-24 X 4-1/2 Hex Head Zinc

The Wacker Neuson is a genuine OEM Screw 3/8-24 X 4-1/2 Hex Head Zinc designed for the CT48 series walk-behind concrete power trowels, including the CT48-13A-V, CT48AVP, and CT48AVT models. As a direct OEM part, the is manufactured to the exact thread specification, length, and zinc coating standard required by these machines, ensuring a correct, trouble-free installation every time. This fastener is sourced directly through the Wacker Neuson parts network, so you can be confident it matches the original component your trowel was built with. Whether you are completing a scheduled service or replacing a damaged fastener, this is the exact screw your machine calls for.

Key Features

• Exact Thread and Length Specification — 3/8-24 fine-thread pitch at 4-1/2 inches matches the OEM fastener spec, ensuring full thread engagement without overtorque risk.
• Zinc-Coated for Corrosion Resistance — The zinc finish provides a protective barrier against moisture and jobsite exposure, helping the fastener hold its integrity over the service life of the trowel.
• Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5000150129 meets the same material and dimensional standards as the fastener originally installed at the factory.
• Confirmed CT48 Series Fitment — Verified for the CT48-13A-V, CT48AVP, and CT48AVT walk-behind power trowels, including standard and CE-marked variable-speed configurations.
• Structural Integrity Where It Counts — A correctly spec'd hex head fastener maintains the clamping force required to keep critical trowel components securely assembled during operation; an incorrect or worn screw can lead to loosening and component misalignment.

A hex head cap screw like the Wacker Neuson 5000150129 serves as a structural fastener, clamping and securing components within the trowel assembly to maintain alignment and prevent movement during operation. The 3/8-24 fine-thread designation provides a higher thread count per inch than a coarse-thread equivalent, delivering greater clamping force and resistance to vibration loosening — a critical characteristic in power trowel applications where the machine generates sustained rotational forces across the finishing pass. A missing, stripped, or incorrect replacement screw can compromise the integrity of the assembly it secures, leading to component shift, accelerated wear, or potential machine downtime.
