Wacker Neuson 5000011421 Screw M12 X 40 Hex Head

The Wacker Neuson is a genuine OEM Screw M12 X 40 Hex Head designed for an exceptionally wide range of Wacker Neuson equipment, including BS and DS vibratory rammers, BPU and DPU reversible vibratory plates, BPS and APS battery-powered vibratory plates, CRT ride-on trowels, PTS trash pumps, LTN and LTW light towers, HSH hydronic surface heaters, and RS single-drum vibratory rollers. As a genuine Wacker Neuson OEM part, is manufactured to the exact material grade, thread pitch, and dimensional specification called out in the original engineering documentation — ensuring proper clamp load and torque retention across all listed applications. This hex head screw installs as a direct replacement with no rework required, making it a straightforward service item whether you are overhauling a rammer, servicing a vibratory plate, or maintaining a light tower. With fitment spanning dozens of current and legacy Wacker Neuson models, confirming your machine's model number against the fitment list before ordering is always recommended.

Key Features

• Correct Thread and Grade Specification — Manufactured to the exact M12 x 40 thread pitch and tensile grade specified by Wacker Neuson, delivering the clamp load these assemblies depend on.
• Hex Head Drive for Positive Torque Application — The six-sided head allows full torque tool engagement, so the fastener can be driven to the correct specification without slipping or rounding.
• Broad Cross-Platform Fitment — A single part number covers BS and DS rammers, BPU and DPU reversible vibratory plates, BPS and APS battery plates, CRT ride-on trowels, PTS trash pumps, LTN and LTW light towers, HSH surface heaters, and RS rollers — useful for mixed fleets carrying one part for multiple machines.
• Genuine OEM Sourcing — Produced by Wacker Neuson to the same material and dimensional standard as the fastener installed at the factory, preserving structural integrity at all bolted joints where this screw is specified.
• Critical Structural Fastener — A stretched, corroded, or under-torqued M12 fastener in a vibratory machine can allow joints to shift under high-frequency loading, leading to accelerated wear or component separation; replacing with the correct OEM item restores designed clamping force.

The Wacker Neuson 5000011421 Screw M12 X 40 Hex Head is a metric hex head cap screw used to fasten structural and mechanical assemblies across multiple Wacker Neuson machine families. In vibratory compaction equipment — rammers and plate compactors — fasteners at this size are typically used to secure housings, engine mounts, exciter assemblies, and wear components that are subjected to continuous high-frequency vibration; maintaining correct torque at these joints is essential to preventing joint loosening and component damage over time. When a fastener of this type stretches, strips, or corrodes, the clamping force at the joint drops below specification, which can result in movement between mated surfaces, fretting wear, or outright mechanical failure — making prompt replacement with the correct OEM screw the most reliable course of action.
