Wacker Neuson 5000155247 Screw M12X35 10.9 Hex Serrated Flange

The Wacker Neuson is a genuine OEM Screw M12X35 10.9 Hex Serrated Flange designed for the G-Series portable generators and LTW-Series light towers. This hardened-grade 10.9 metric fastener is sourced directly from Wacker Neuson, ensuring it meets the original torque, thread pitch, and load specifications called out in the factory service documentation. Confirmed fitment spans a wide range of G-Series skid-mounted and mobile generators — including G25, G50, G70, G85, G100, G110, G120, G125, G130, and G150 models — as well as LTW6K, LTW8K, LTW20Z-1, and LTW20Z-3 light towers across standard, cold-weather, and custom configurations. A CRT48-57K ride-on concrete trowel application is also covered under this part number.

Key Features

• Grade 10.9 High-Tensile Rating — The 10.9 property class designation means this fastener is engineered to handle the high-clamp-load demands of structural and drivetrain joints on heavy equipment frames, not a generic hardware-store substitute.
• Integrated Hex Serrated Flange — The serrated flange bearing surface bites into the mating material to resist loosening under vibration — critical on generators and light towers that run continuously for extended periods.
• Genuine OEM Sourcing — Supplied as an authentic Wacker Neuson OEM part, meaning the thread form, shank length, and flange diameter match the original hardware specifications without adaptation.
• Broad Cross-Family Fitment — One part number covers G-Series generators (G25 through G150), the full LTW6K, LTW8K, LTW20Z-1, and LTW20Z-3 light tower range, and the CRT48-57K trowel, consolidating your parts ordering across multiple equipment types.
• Correct Hardware Protects Surrounding Components — Using an undersized or lower-grade fastener in a high-load joint risks bolt stretch, fatigue failure, and damage to the housing or frame it secures; the correct grade and geometry eliminate that risk.

A hex serrated flange screw combines three functions in a single fastener: the hex drive provides high installation torque, the flange distributes clamping load across a wider bearing area, and the serrations on the underside of the flange lock against the mating surface to prevent loosening from vibration. On generators and light towers — equipment that operates under sustained engine vibration for hours at a time — fastener security is directly tied to structural integrity and continued operation. A fastener that backs out or fails in fatigue can allow panels, mounting brackets, or structural covers to shift, leading to secondary damage that far outweighs the cost of the original hardware.
