Wacker Neuson 5000029116 Screw M6 X 1 X 20 Flange Lock

The Wacker Neuson Screw M6 X 1 X 20 Flange Lock is a genuine OEM fastener designed for a wide range of Wacker Neuson equipment including G-Series skid-mounted mobile generators, LTN6 and LTW light towers, HI indirect-fired air heaters, GPS and GS portable generators, and RD tandem rollers. Sourced directly from Wacker Neuson, this fastener meets the exact dimensional and material specifications used in original production assemblies. The is the correct replacement when servicing panels, housings, guards, or structural brackets across these product families. Confirm your model number before ordering to ensure proper fitment.

Key Features

• Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's exact M6 x 1 x 20 thread pitch and flange geometry, ensuring the clamping load and torque retention match the original assembly specification.
• Integrated Flange Lock Design — The built-in serrated flange distributes clamping force over a wider bearing surface and bites into the mating material to resist loosening under vibration — critical on generators, heaters, and rollers that run under continuous load.
• Broad Cross-Family Fitment — A single part number covers G-Series generators (G25 through G150), LTN6/LTN8/LTW light towers, HI series indirect-fired air heaters (HI260, HI750, HI900, HI1000), GPS/GS portable generators, and RD tandem rollers including RD7H and RD880V variants.
• Drop-In Service Replacement — Matches the thread form, length, and flange outer diameter of the original fastener, so it seats correctly in existing tapped holes or with standard M6 hardware without rework.
• Maintains Structural Integrity Under Vibration — A failed or missing flange lock screw can allow covers, guards, and mounting brackets to shift or separate during operation; replacing with the correct OEM part restores the designed clamping and keeps assemblies secure.

A flange lock screw combines a standard metric hex-head cap screw with an integrated serrated washer flange formed as a single piece. The flange's serrations bite into the surface of the fastened component when the screw is tightened, creating mechanical resistance to rotational loosening that would otherwise occur from engine vibration, thermal cycling, or road transport on trailer-mounted equipment. On Wacker Neuson generators, light towers, and heaters, these screws are commonly used to secure enclosure panels, mounting brackets, and component housings where a separate lock washer would be impractical or could be omitted during reassembly. When a flange lock screw is stripped, missing, or replaced with a plain screw, the joint loses its vibration resistance and fastener back-out becomes likely over time, potentially allowing structural or protective components to loosen in service.
