Wacker Neuson 5000115628 Screw M10X40 Hex Serrated Flange Zinc Plated

The Wacker Neuson is a genuine OEM Screw M10X40 Hex Serrated Flange Zinc Plated designed for the WB16A series Power Buggies and HI750 series Indirect Air Heaters. Sourced directly from Wacker Neuson, this fastener meets the original engineering specification for thread pitch, flange geometry, and zinc plating grade used at the factory. It is confirmed to fit a wide range of WB16A Power Buggy configurations — including electric start, four-wheel drive, and self-dumping variants — as well as HI750D, HI750G, and HI750GM Indirect Air Heater models. Using the correct OEM fastener ensures proper clamping load and corrosion protection in the demanding environments these machines operate in.

Key Features

• Genuine OEM Specification Threading — M10x40 thread dimensions match the original fastener exactly, ensuring full thread engagement without stripping or cross-threading on reinstallation.
• Serrated Flange Locking Design — The integrated hex serrated flange bites into the mating surface under torque, providing vibration-resistant clamping without the need for a separate lock washer.
• Zinc Plated for Corrosion Resistance — The zinc plating guards against rust and oxidation, which is especially important on equipment exposed to outdoor jobsite conditions, moisture, and temperature swings.
• Broad Fitment Across WB16A and HI750 Families — A single part number covers the full WB16A Power Buggy lineup and HI750D, HI750G, and HI750GM Indirect Air Heater configurations, making it a practical stock item for mixed fleets.
• Maintains Structural Integrity — A failed or incorrect fastener in these assemblies can lead to loose panels, shifting components, or unsafe operation; the correct OEM screw restores the designed clamping force and keeps critical assemblies secure.

A hex serrated flange screw combines a standard hex-head bolt with an integrated flanged washer face that features radial serrations on its bearing surface. When the screw is tightened, the serrations grip the mating material and resist loosening from vibration — a critical characteristic on equipment like power buggies and indirect air heaters that experience constant mechanical vibration and thermal cycling during operation. When this fastener is missing, damaged, or replaced with a non-serrated equivalent, assemblies can work loose over time, leading to misalignment, panel movement, or component separation that may compromise both performance and operator safety.
