The Wacker Neuson Hex Jam Nut Bm5 is a genuine OEM fastener designed for the CT30, CT36, and CT48 series walk-behind concrete power trowels, as well as the RT560 and RT820 vibratory trench rollers. Sourced directly from Wacker Neuson, this part carries the same specifications as the hardware installed at the factory. It fits across a wide range of CT-series trowel configurations — including gasoline, diesel, and variable-speed models — as well as electric-start variants in both standard and CE-specification builds. When you need an exact replacement, part number ensures you're installing the correct fastener the first time.
Key Features
- Genuine OEM Hardware Spec — Manufactured to Wacker Neuson's precise thread form and hardness rating for the Bm5 jam nut profile, ensuring correct clamping force and thread engagement on reassembly.
- Drop-In Replacement — Matches the original fastener's dimensions exactly, threading directly onto the existing stud or bolt without any modification to surrounding hardware.
- Broad CT-Series Coverage — Fits CT30, CT36, and CT48 walk-behind power trowels in gasoline, diesel, electric-start, variable-speed, and CE-specification configurations.
- RT Trench Roller Fitment — Also verified for the RT560 and RT820 vibratory trench roller families, making this a versatile fastener across Wacker Neuson's concrete and compaction lineup.
- Prevents Fastener Loosening Under Vibration — Jam nut design locks against the primary nut to resist self-loosening caused by the sustained vibration inherent in trowel and roller operation.
A hex jam nut is a thin, low-profile locking nut threaded against a standard nut or shoulder to prevent rotation and fastener loosening under load or vibration. On power trowels and trench rollers, which generate continuous vibration during operation, maintaining correct fastener torque is critical — a loose or missing jam nut can allow assembled components to shift, leading to play in moving parts, accelerated wear, or mechanical failure. Replacing a worn or damaged jam nut with the correct OEM part restores proper clamping integrity and keeps the assembly secure through demanding work cycles.
