The Wacker Neuson is a genuine OEM Lock Screw M6 X 40 Hex designed for the GP3800A, GP5600A, GP6600A, and GPS5600A portable generator series. As a factory-sourced fastener, the is manufactured to the exact thread pitch, length, and head geometry specified for these machines, ensuring a secure and correct installation every time. This screw is compatible across multiple GP-series configurations, including CARB GFI and wheel-kit variants, making it a straightforward service item for technicians working across the full portable generator lineup.
Key Features
- Genuine OEM Thread Specification — M6 X 40 metric sizing matches the original fastener exactly, with no risk of cross-threading or improper engagement in the generator housing.
- Locking Design for Vibration Resistance — The locking feature on this screw is critical in a generator application where continuous engine vibration can work standard fasteners loose over time.
- Hex Drive for Positive Torque — The hex head allows proper torque application with standard tooling, supporting a secure, repeatable installation during service or assembly.
- Broad GP-Series Compatibility — Fits the GP3800A, GP5600A, GP6600A, and GPS5600A generator models, including premium portable and CARB GFI configurations, as well as wheel-kit variants.
- Factory-Sourced Replacement — Sourced directly from Wacker Neuson, this part carries the same part number used in original assembly, so you can confirm fitment with confidence against your machine's service documentation.
A lock screw serves as a threaded fastener with an integrated locking mechanism — typically a deformed thread or nylon patch — that resists loosening caused by vibration and dynamic loads. In portable generators like the GP and GPS series, fasteners in the engine, frame, and panel assemblies are subjected to constant vibration during operation, making the locking feature essential to maintaining structural integrity and safe enclosure retention. When a lock screw fails, strips, or goes missing, the affected component can shift, rattle, or detach, potentially causing damage to surrounding parts or creating a safety concern during operation.
