Wacker Neuson 5000111040 Screw M8X12 Hexagon Head Serrated Flange

The Wacker Neuson is a genuine OEM Screw M8X12 Hexagon Head Serrated Flange designed for use across the G7AI generator, RD11 hydrostatic double drum vibratory roller, and LTN6 and LTN8 series light tower product families. As a factory-sourced fastener, the is manufactured to the exact dimensional and material standards Wacker Neuson specifies for these machines. This screw is confirmed to fit a wide range of LTN6L-V, LTN6K-V, LTN8K-V, and LTN6LE-V light tower configurations in addition to RD11A, RD11V, and RD11AEC roller variants. Ordering by part number ensures you receive the correct M8 x 12 mm serrated flange fastener without guesswork or modification.

Key Features

• Genuine OEM Fastener Specification — Manufactured to Wacker Neuson's exact thread pitch, head geometry, and flange serration profile, ensuring consistent clamping force and vibration resistance in service.
• Integrated Serrated Flange Design — The serrated underside bites into the mating surface on installation, locking the fastener against loosening under machine vibration without requiring a separate lock washer.
• Broad Cross-Family Fitment — A single part number covers the G7AI generator, RD11 series tandem rollers, and the full LTN6 and LTN8 vertical mast light tower lineup, making it a practical stocking fastener for mixed fleets.
• Correct Torque Retention on High-Vibration Equipment — On vibratory rollers and light towers operating in demanding field conditions, a properly rated serrated flange screw maintains joint integrity where standard hex head fasteners can back out over time.
• Direct OEM Source — Supplied as a genuine Wacker Neuson component, so thread engagement, hardness grade, and surface finish match the original build specification exactly.

A hexagon head serrated flange screw combines the function of a standard hex bolt with a built-in locking flange. The serrations on the flange face grip the mounting surface when torqued down, creating resistance against rotational loosening caused by vibration — a common failure mode on compaction equipment, rollers, and portable power units that cycle continuously in the field. When this type of fastener wears, strips, or is substituted with an incorrect grade or size, joint preload is compromised, which can lead to structural loosening of panels, housings, or mechanical assemblies and accelerate wear on surrounding components. Using the correct OEM-specified fastener like the Wacker Neuson 5000111040 maintains the designed clamping load and keeps critical connections secure across the machine's service life.
