Wacker Neuson 5000179011 M4x20 SBHCS Black Zinc Screw

The Wacker Neuson is a genuine OEM M4x20 SBHCS Black Zinc Screw designed for the CRT48 series ride-on concrete trowels. As a direct OEM replacement, this fastener is manufactured to the same specifications as the original hardware installed at the factory, ensuring proper retention and fit across every compatible CRT48 configuration. It is confirmed to fit the CRT48-35L-PS, CRT48-57K-PS, CRT48-37V-PS, and CRT48-35V-PS power steer models. When maintaining or reassembling your ride-on trowel, using the correct OEM fastener like the ensures structural integrity and keeps every component seated exactly as intended.

Key Features

• Genuine OEM Corrosion Resistance — Black zinc coating provides the same protective finish specified for CRT48 hardware, resisting moisture and oxidation in demanding finishing environments.
• Socket Button Head Design — The SBHCS (socket button head cap screw) profile delivers a low-profile seating surface with hex-key drive, matching the original fastener interface on the CRT48 platform.
• Broad CRT48 Series Compatibility — Fits multiple CRT48 power steer variants including the CRT48-35L-PS, CRT48-57K-PS, CRT48-37V-PS, and CRT48-35V-PS, covering a wide range of ride-on trowel configurations.
• Structural Integrity During Operation — A correctly torqued, properly spec'd fastener keeps panels, guards, and mechanical assemblies securely positioned on the trowel — a loose or incorrect screw can cause component shift or premature wear.
• Direct OEM Sourcing — Sourced directly from Wacker Neuson, this screw carries the same part number used in the original assembly, eliminating guesswork when ordering replacement hardware.

The M4x20 SBHCS Black Zinc Screw is a metric fastener used to secure panels, brackets, or mechanical subassemblies on Wacker Neuson CRT48 ride-on concrete trowels. The socket button head cap screw design allows flush or near-flush seating in tight clearance areas, while the black zinc finish protects the fastener from surface corrosion during washdown and outdoor use. When a fastener like this fails, strips, or goes missing, the assembly it holds can loosen during operation — potentially affecting trowel performance, operator safety, or accelerating wear on surrounding components.
