The Wacker Neuson is a genuine OEM Screw M10 x 20 Hex Head Medium Lock designed for a broad range of Wacker Neuson compaction and concrete finishing equipment, including the CT36-400E walk-behind power trowel, RD7 and RD27 tandem rollers, and RTKx-SC3 trench rollers. As a genuine OEM component, is manufactured to the exact material grade, thread specification, and locking compound rating called out in the original Wacker Neuson build documentation. This fastener is a direct-fit replacement that installs exactly as the original, with no modification required to mating hardware or surrounding components. Sourcing the correct OEM-specified screw matters on high-vibration equipment — an underspec fastener in this application can back out under load, leading to component loosening or structural failure.
Key Features
- Correct Thread Locking Grade: — Medium-lock specification holds under the sustained vibration loads generated by compaction rollers and trowel equipment, resisting back-out without permanently bonding the joint.
- OEM Material and Thread Accuracy: — M10 x 20 sizing is matched to the original Wacker Neuson fastener specification, ensuring proper clamp load and torque values are achievable at installation.
- Hex Head Drive: — Standard hex head format is compatible with common workshop and field tooling, making installation and removal straightforward in tight machine access areas.
- Wide Cross-Family Fitment: — Verified to fit CT36-400E power trowels, RD7, RD7H, RD7He, RD7Ye, and RD27-100/120 tandem rollers, and RTKx-SC3 and RTK82-SC3 trench rollers across multiple serial number ranges.
- Genuine Wacker Neuson OEM Part: — Supplied as an authorized OEM replacement, so thread form, shank length, and locking characteristic match the part this fastener replaces with no guesswork.
- Structural Integrity on High-Vibration Equipment: — Using the correct locking fastener in this application maintains the clamping integrity of critical assemblies; a missing or incorrect screw in a vibrating machine can escalate quickly from a loose joint to component damage.
A hex head medium-lock screw is a threaded fastener with a pre-applied or specified medium-strength locking feature — typically achieved through thread geometry, a locking patch, or a specified adhesive grade — that prevents the screw from loosening under vibration and dynamic loads. On equipment like tandem rollers and trench rollers, which generate continuous vibratory force during operation, maintaining correct fastener clamping load across assemblies is essential to structural integrity. When a fastener of the wrong locking specification is installed, it may gradually back out during operation, allowing components to shift, wear unevenly, or disengage entirely — making correct replacement with the OEM-specified part critical to safe, reliable machine operation.
