The Wacker Neuson is a genuine OEM Screw M16 X 40 Hex Head designed for a broad range of Wacker Neuson portable power, lighting, and pumping equipment. As a sourced-from-the-factory OEM component, the is manufactured to the exact dimensional and material specifications required by the original equipment. This fastener fits across multiple G-Series portable generators (G25, G50, G70, G100, G120, G150, G180, G240), LTW and LTV and LTN light tower series, PT6LT and PT6LS trash pumps, RD27 tandem rollers, and E1250-Series hydronic heaters — making it one of the most widely shared structural fasteners in the Wacker Neuson lineup.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to exact M16 x 40 thread pitch and hex head dimensions, ensuring correct torque loading and secure clamping across all listed applications.
- Drop-In Hex Head Design — Standard hex head profile accepts common drive tools used in field service, allowing straightforward installation or replacement without special tooling.
- Exceptionally Wide Fitment Coverage — A single part number covers G25 through G240 generators, LTW6K through LTW20Z light towers, PT6LT and PT6LS trash pumps, RD27 tandem rollers, and E1250 hydronic heaters.
- Structural Holding Power — M16 fasteners at this grade carry significant clamping loads; using the correct replacement prevents joint loosening, frame vibration fatigue, and component misalignment on high-cycle equipment.
- Verified OEM Part Number — Ordering by Wacker Neuson part number 5000011521 confirms you are receiving the exact fastener specified in the factory bill of materials — critical when servicing equipment under tight tolerances.
A hex head cap screw is a primary structural fastener used to clamp major assemblies, frames, mounting brackets, and covers together on heavy equipment. The M16 x 40 designation specifies an outer thread diameter of 16 mm and a 40 mm grip length, which determines how deeply the screw draws mating surfaces together. When a fastener of this type loosens, corrodes, or fails, the joint it secures can shift under load or vibration — leading to premature wear of surrounding components, increased noise, or, in severe cases, structural separation. Replacing a worn or damaged screw with the correct OEM specification restores the designed clamping force and keeps the assembly properly torqued for continued safe operation.
