Wacker Neuson 5000163945 Screw M8X16 Button Head Black Zinc 10.9

The Wacker Neuson is a genuine OEM Screw M8X16 Button Head Black Zinc 10.9 designed for a wide range of Wacker Neuson tandem rollers and concrete power trowels. This fastener is factory-sourced to ensure correct thread pitch, head geometry, and surface finish across every application it serves. Compatible models include the RD12, RD16, and RD27 series tandem rollers, the CRT60 series ride-on concrete trowels, and the GPS9700 portable generator. As a genuine OEM part, the meets the same specifications as the hardware installed at the factory, so you can reinstall with confidence and get the machine back to work without second-guessing compatibility.

Key Features

• Grade 10.9 High-Tensile Strength — The 10.9 property class rating means this screw delivers the clamping force required for structural and vibration-exposed joints found throughout Wacker Neuson roller and trowel assemblies.
• Black Zinc Corrosion Protection — The black zinc finish provides a protective coating that resists rust and surface oxidation, extending service life in outdoor and wet-environment applications common to compaction and finishing work.
• Button Head Profile for Low-Clearance Installations — The low-profile button head allows secure fastening in tight or recessed mounting locations where a standard hex head would interfere with surrounding components.
• Genuine OEM Part for Exact Thread and Torque Specs — Sourced directly from Wacker Neuson, part number 5000163945 matches the original M8x16 thread and torque specification, eliminating guesswork when torquing to service manual values.
• Broad Cross-Family Fitment — Confirmed fit across RD12, RD16, and RD27 series tandem rollers, CRT60 series ride-on concrete trowels, and GPS9700 portable generators — one part number covering a wide service inventory.

A button head cap screw is a threaded fastener used to clamp two or more components together in applications where a low-profile head is necessary to clear adjacent hardware or panels. The M8x16 size specifies an 8 mm thread diameter and 16 mm grip length, making it suitable for medium-duty structural joints that must maintain secure clamping force under continuous vibration — a common condition in compaction and concrete finishing equipment. When a fastener of this type fails, loosens, or is replaced with an incorrect grade, the joint can shift under load, leading to accelerated wear of surrounding components or loss of structural integrity in the assembly.
