Wacker Neuson 5000157166 Carr Bolt M8X45 Blk Med Loc Zn

The Wacker Neuson is a genuine OEM Carr Bolt M8X45 Blk Med Loc Zn designed for RT56, RT82, RTLx, RTKx, and RTx series remote-controlled trench rollers, as well as RD27 tandem rollers. Sourced directly from Wacker Neuson, this fastener matches the exact specification — including thread pitch, length, zinc finish, and medium-strength thread-locking patch — called out in the original engineering drawings. It fits across a broad range of SC2 and SC3 generation trench roller configurations, including smooth-drum and padfoot variants, as well as Compatec-equipped models and the RD27-100 and RD27-120 tandem roller family.

Key Features

• OEM Thread-Lock Integrity — The pre-applied medium-strength locking patch on 5000157166 delivers the same thread-retention force as the original assembly, preventing fastener back-out under continuous vibration loads typical of trench roller operation.
• Zinc-Plated Corrosion Protection — The black zinc finish resists moisture and surface oxidation, holding up in trench and compaction environments where bare hardware would corrode and seize.
• Exact M8X45 Dimensional Spec — At M8 thread diameter and 45 mm length, this bolt drops into existing bores and tapped holes without rework, matching the torque spec and clamp load required by the original joint design.
• Broad Trench Roller and Tandem Roller Coverage — Confirmed fitment across RT56-SC, RT56-SC2, RT82-SC, RT82-SC2, RTLx-SC3, RTKx-SC3, RTx-SC2, and RD27-100/120 machine families, covering both current and earlier production generations.
• Vibration-Critical Joint Reliability — Loose or incorrect fasteners on a vibratory roller can lead to structural movement, component misalignment, and accelerated wear on surrounding parts; using the correct OEM bolt with the right locking patch maintains joint integrity throughout the service interval.

A carriage bolt with a medium-strength thread-locking patch is a fastener engineered to clamp two or more components together at a defined torque value while resisting self-loosening caused by vibration. On remote-controlled trench rollers and tandem rollers, drivetrain, frame, and drum assembly joints are subjected to continuous high-frequency vibration during operation — conditions that will gradually back out a standard unfastened bolt. The zinc coating on part 5000157166 protects the fastener shank from corrosion in soil and moisture contact, ensuring the bolt can be removed cleanly at the next service interval without galling or seizing in the tapped bore. A missing, stretched, or incorrect-length bolt in these joints can result in component shift, abnormal wear on adjacent hardware, and ultimately structural failure of the bolted assembly.
