Wacker Neuson 5000011418 Screw M12 X 55 Hhcs 8.8 Zinc

The Wacker Neuson is a genuine OEM Screw M12 X 55 Hhcs 8.8 Zinc designed for a wide range of Wacker Neuson equipment, including PT3 series centrifugal trash pumps, VP1340, VP1550, and VP2050 single-direction vibratory plates, BS62 and BS68 gasoline rammers, and AS62e and AS68e battery-powered rammers. As a factory-sourced fastener, the is manufactured to the exact grade 8.8 zinc-plated specification required by Wacker Neuson, ensuring a correct and secure fit across every compatible application. This hex head cap screw is a genuine OEM component, meaning it leaves the factory to the same material and dimensional standards as the original hardware installed at the time of build. Keeping critical fasteners at OEM specification is essential for maintaining the structural integrity and performance of compaction and pump equipment operating under sustained load and vibration.

Key Features

• Grade 8.8 Tensile Strength — Medium-carbon steel construction meets the grade 8.8 rating, delivering the shear and tensile resistance required in high-vibration compaction and pump applications.
• Zinc-Plated Corrosion Protection — The zinc coating shields the fastener against rust and surface degradation in wet, muddy, and outdoor jobsite conditions common to pumping and compaction work.
• Genuine OEM Sourcing — Manufactured to the same material and dimensional specification as the original hardware, so thread pitch, head geometry, and torque values match Wacker Neuson engineering requirements exactly.
• Broad Cross-Family Compatibility — A single part number covers PT3 trash pumps, VP-series vibratory plates, BS62/BS68 rammers, and AS-series battery rammers, making it a useful stock item for mixed Wacker Neuson fleets.
• Structural Integrity Under Load — A correctly rated fastener keeps housings, guards, and structural assemblies clamped at the designed preload; an under-spec or worn screw can allow movement that damages mating components over time.

A hex head cap screw (HHCS) is a precision-threaded fastener used to clamp structural and mechanical assemblies together at a specified preload. In construction equipment like vibratory plates, rammers, and trash pumps, fasteners are exposed to continuous vibration, impact, and outdoor moisture, all of which can accelerate wear or corrosion in an incorrect or substandard bolt. The M12 X 55 size and grade 8.8 rating are not interchangeable with lower-grade hardware — substituting an incorrect grade risks under-clamping critical joints, which can lead to component loosening, accelerated wear on mating surfaces, or structural failure during operation. Replacing worn or damaged fasteners with the correct OEM-specification screw restores the assembly to its designed clamping load and keeps the machine operating safely within its engineered parameters.
