The Wacker Neuson is a genuine OEM Carriage Bolt M8X20 Bz 8.8 designed for RD12, RD16, and CB14B series tandem rollers used in soil and asphalt compaction applications. Sourced directly from Wacker Neuson, this fastener meets the original engineering specification for grade 8.8 tensile strength, ensuring it performs exactly as intended in your machine. Compatible models include the RD12-90, RD12A-90, RD16-90, RD16-100, and CB14B-900/1000 tandem rollers, as well as select HTC15 trench roller configurations. When hardware integrity matters on compaction equipment running in demanding site conditions, installing the correct OEM-specified fastener keeps every assembly secure and properly torqued.
Key Features
- Grade 8.8 Tensile Strength — Manufactured to Bz 8.8 specification, delivering the shear and tension resistance required for structural fastener positions on vibratory compaction equipment.
- Genuine OEM Part — Supplied by Wacker Neuson as part number 5000163954, matching the original bolt used on the production line — no guesswork on thread pitch, shank length, or head diameter.
- Broad Tandem Roller Fitment — Confirmed fitment across RD12-90, RD12A-90, RD16-90, RD16-100, CB14B-900, and CB14B-1000 series rollers, including standard, foldable ROPS, and hydrostatic configurations.
- Carriage Head Design — The rounded head and square neck of the M8X20 carriage bolt self-locks against the mating surface during installation, allowing single-sided fastening in panel and frame assemblies.
- Corrosion-Resistant Finish — Bz (bronze/zinc) designation indicates a protective surface treatment suited to the wet, abrasive environments typical of roller operation on asphalt and compacted soil.
A carriage bolt is a structural fastener used throughout the frame, hood, ROPS, and panel assemblies of tandem rollers. Its smooth domed head and square shoulder beneath it are designed to grip the material it passes through, preventing rotation as the nut is tightened — making it ideal for joints where access is limited to one side. On compaction equipment like the RD and CB14B series, these bolts are subjected to constant vibration during operation; using a fastener of the correct grade and dimensions is essential to maintaining joint integrity. A worn, stripped, or incorrect-grade bolt can allow panels or structural components to loosen over time, leading to rattling, misalignment, or more serious mechanical issues if left unaddressed.
