The Wacker Neuson M12 Serrated Flanged Hex Nut is a genuine OEM fastener designed for RD11 hydrostatic double drum vibratory rollers and the full range of LTW and LTV light towers. Sourced directly from Wacker Neuson, this hardware matches the exact specification used in original production. It fits across a broad range of LTW6K, LTW8K, LTW20Z1, LTW20Z3, and LTV series light towers, as well as RD11A and RD11V tandem rollers — covering standard, cold weather, custom, and Tier 4i configurations. When you need to restore a fastening point to its original condition, is the correct, verified part.

Key Features

  • Genuine OEM Flanged Hex Construction — The integrated serrated flange distributes clamping load evenly and bites into the mating surface to resist vibration-induced loosening — critical on compaction and power generation equipment.
  • Correct M12 Thread Specification — Matches the thread pitch, shank dimensions, and flange diameter specified for the original assembly, ensuring full thread engagement without rework.
  • Wide Fitment Across Two Equipment Families — Verified for RD11A and RD11V tandem rollers and a broad range of LTW6K, LTW8K, LTW20Z1, LTW20Z3, and LTV series light towers in standard, cold weather, custom, and Tier 4i variants.
  • Vibration Resistance Built In — The serrated bearing face locks under dynamic load, so joints stay tight through continuous machine operation rather than gradually backing off over time.
  • Structural Integrity Maintained — Using the correct OEM fastener grade preserves the rated clamping force of the joint; substituting an incorrect grade or style risks joint fatigue and potential structural failure at the connection point.

A serrated flanged hex nut combines a standard hex nut with a wide, load-spreading flange and a ring of sharp serrations on the bearing face. The flange eliminates the need for a separate washer by distributing the fastener's clamping force over a larger surface area, reducing the risk of the nut pulling through or distorting the mating material. The serrations bite into the surface as the nut is torqued down, creating a mechanical lock that resists the loosening effect of vibration — a constant force on both compaction rollers and engine-driven light towers. When a serrated flanged nut wears, loses its serration profile, or is replaced with a plain nut, the joint can gradually back off under load, leading to loose panels, structural connections, or component mounts that may cause operational faults or safety concerns.
