The Wacker Neuson is a genuine OEM Screw 1/4-20 X 4-1/8 Shoulder designed for the CT48BDT walk-behind concrete power trowel, the B 3000 gasoline power unit for internal vibrators, and the PT3B 3-inch centrifugal trash pump. As a direct Wacker Neuson OEM part, the is manufactured to the same specification as the original hardware, ensuring consistent fit and function across all three machine families. Verify your model number against the fitment list before ordering to confirm compatibility with your specific unit.
Key Features
- Precision-Turned Shoulder Diameter — The machined shoulder section provides a controlled bearing surface, ensuring the fastener seats correctly and maintains accurate component alignment without relying solely on thread engagement.
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this screw meets the original material grade and dimensional tolerances specified for the 1/4-20 X 4-1/8 shoulder configuration.
- Cross-Platform Fitment — Confirmed for the CT48BDT walk-behind concrete trowel, B 3000 gasoline power unit for internal vibrators, and PT3B 3-inch centrifugal trash pump — three distinct Wacker Neuson machine families sharing this hardware specification.
- Direct Threaded Replacement — The 1/4-20 thread form is a standard unified coarse pitch, allowing the screw to thread directly into existing tapped holes with no rework or re-tapping required.
- Fastener Integrity Under Load — A correctly installed shoulder screw transfers shear loads through the shoulder rather than the threads, protecting both the fastener and the surrounding components from accelerated wear.
A shoulder screw is a precision fastener with a smooth, unthreaded cylindrical section — the shoulder — between the head and the threaded tip. The shoulder acts as a locating pin or pivot surface, carrying shear forces through the cylindrical body rather than through the threads, which extends the service life of both the fastener and the mating parts. When a shoulder screw becomes worn, bent, or stripped, the components it locates can shift out of alignment or develop excess play, leading to accelerated wear on nearby parts and inconsistent machine performance.
