Wacker Neuson 5000154524 Screw M12X140-8.8 Hexhead BN57 ZP

The Wacker Neuson is a genuine OEM Screw M12X140-8.8 Hexhead BN57 ZP designed for the G12, G25, G50, G70, and G85 series skid-mounted mobile generators, including standard and cold-weather configurations. Sourced directly from Wacker Neuson, this fastener is manufactured to the same specification as the original hardware installed at the factory, ensuring a correct, secure fit in its designated mounting location. Compatible across multiple G-series generator variants, part number is the right choice whether you are servicing a standard skid-mounted unit or a cold-weather-equipped model.

Key Features

• OEM-Grade Fastener Specification — M12x140 hex head bolt in property class 8.8, delivering the tensile strength and torque rating required for structural mounting applications on generator frames.
• Zinc-Plated Corrosion Resistance — ZP (zinc-plated) finish provides a protective barrier against moisture and surface oxidation, important for equipment operating in outdoor or cold-weather environments.
• Drop-In Replacement Hardware — Thread pitch, shank length, and head profile match the original fastener exactly, allowing direct installation without modification to the mating components.
• Broad G-Series Compatibility — Verified fitment across G12, G25, G50, G70, and G85 skid-mounted mobile generators, including standard and cold-weather variants.
• Structural Integrity Where It Counts — Using the correct grade and length fastener ensures critical generator assemblies remain properly torqued and secured during transport and operation — an undersized or incorrect bolt risks joint failure under vibration loads.

A hex head bolt like the 5000154524 serves as a structural fastener that clamps and secures major assemblies — such as engine mounts, generator frames, or skid components — within the G-series mobile generator. The M12x140 designation specifies a 12 mm diameter thread on a 140 mm shank, while the 8.8 property class indicates a medium-high-strength steel capable of handling the clamping loads and vibration stresses common in generator applications. When a fastener of this type is missing, stripped, or replaced with an incorrect grade, it can compromise the structural rigidity of the assembly and lead to accelerated wear on surrounding components or unsafe equipment movement during operation.
