The Wacker Neuson Screw M12 x 30-10.9 Hex Head is a genuine OEM fastener designed for a wide range of Wacker Neuson tandem rollers, single-drum vibratory rollers, portable generators, and light towers. As a direct OEM replacement, is manufactured to the exact grade 10.9 tensile specification required by the original design, ensuring the correct clamping force and torque retention in each application. Fitment spans the RD12 and RD16 tandem roller series, RS800 and RS800A single-drum roller series, G25, G50, and G70 skid-mounted generator series, and LTV6K, LTV8K, and LTV6L light towers.

Key Features

  • Grade 10.9 High-Tensile Construction — Manufactured to the 10.9 strength classification, delivering the precise clamp load and shear resistance specified by Wacker Neuson engineers for critical structural joints.
  • Genuine OEM Part — Sourced directly from Wacker Neuson, 5000020378 matches the exact thread pitch, head geometry, and surface treatment of the original fastener for a drop-in installation.
  • Broad Cross-Family Fitment — Confirmed for RD12 and RD16 tandem rollers, RS800/RS800A/RS800V single-drum rollers, G25/G50/G70 generator series, and LTV6K/LTV8K/LTV6L light towers — one part number across multiple equipment families.
  • Maintains Joint Integrity Under Vibration — High-strength fasteners at this grade resist loosening in high-vibration environments typical of compaction equipment and generator frames, helping to preserve structural alignment over extended service cycles.
  • Hex Head Drive — Standard hex head profile is compatible with common wrench and socket tooling, allowing straightforward installation and removal during routine service and assembly.

A hex head cap screw is a structural fastener used to clamp and secure machine components together across frames, housings, and mounting assemblies. The grade rating — in this case 10.9 — indicates the tensile strength of the fastener; a higher grade means the bolt can sustain greater clamping force without stretching or yielding. Using an incorrect grade or a worn fastener in a high-torque or high-vibration joint can lead to joint movement, component misalignment, or fastener failure, which can compromise both machine performance and operator safety. Replacing worn or damaged hardware with the correct OEM-specified grade fastener restores the engineered integrity of the joint.
