The Wacker Neuson Screw M12 X 20 12.9 Soc is a genuine OEM fastener designed for RTKx-SC3 and RTK82-SC3 trench rollers as well as the VP series vibratory plate compactors, including VPA, VPX, VPY, and VPR models. As a direct OEM replacement, the meets the original material grade and dimensional specifications required for secure, load-bearing assembly connections on these machines. Fitment spans multiple RTKx-SC3 and RTK82-SC3 configurations, including Compatec-equipped variants, as well as diesel and standard VP series vibratory plates. Sourcing the correct grade 12.9 socket-head fastener ensures structural integrity is maintained at every fastened joint.
Key Features
- Grade 12.9 High-Tensile Construction — The 12.9 property class rating delivers the high clamping force and shear resistance required at critical structural joints on trench rollers and vibratory plate compactors.
- Genuine OEM Part — Supplied directly through the Wacker Neuson OEM supply chain, confirming correct thread pitch, head dimensions, and material spec for the 5000081333 application.
- Socket-Head Drive Design — The internal hex (socket) drive allows precise torque application in tight assembly clearances common to RTKx-SC3 roller frames and VP compactor decks.
- Broad Fitment Across Two Machine Families — Verified for RTKx-SC3 and RTK82-SC3 trench rollers (including Compatec configurations) and VPA, VPX, VPY, and VPR series vibratory plate compactors.
- Prevents Joint Failure Under Vibration — A worn, incorrect, or under-grade fastener at a high-vibration joint can lead to loosening and structural damage; replacing with the correct OEM-spec screw restores joint integrity.
The Screw M12 X 20 12.9 Soc is a high-tensile, socket-head cap screw used to secure structural and mechanical assemblies on vibratory compaction equipment. The 12.9 grade designation indicates an exceptionally high tensile and proof load rating, making it suited for joints that experience sustained vibration, heavy loading, or significant clamping force requirements. When a fastener in this role is missing, stripped, or replaced with an incorrect grade, joint clamping force drops and connected components become susceptible to movement, wear, and ultimately failure — making like-for-like OEM replacement the correct approach.
