Key Features
- OEM-Matched Fastener Specification — manufactured to the same thread pitch, diameter, and slot geometry as the original Bomag castle nut, ensuring the cotter pin seats correctly and the locking function performs as intended
- Direct OEM Replacement — installs in place of the original hardware with no rework or modification to the mating components
- Broad Tandem Roller Coverage — compatible with Bomag BW 80 AD-2, BW 80 ADS, BW 90 AD-2, BW 90 AC-2, BW 100 ADM-2, BW 161 ADH-4, BW 190 AD-4, BW 190 AD-4 AM, BW 202 AD-4, and BW 203 AD-4 AM tandem rollers
- Secure Locking Under Load — the castellated design accepts a cotter pin to prevent the nut from backing off under vibration and dynamic load, which is essential on compaction equipment subject to continuous operational stress
- Genuine Bomag Part — part number 08151104 is an authentic Bomag component, giving you confidence that the fitment data and material grade are exactly as the machine was built to accept
A castle nut — also called a castellated nut — is a hex nut with slots cut into one end that allow a cotter pin or safety wire to pass through a drilled shaft or bolt, locking the nut in position. On tandem rollers, these nuts are used in assemblies where vibration and repeated loading would cause a standard nut to loosen over time, such as axle, drum, and steering pivot connections. A worn, stripped, or missing castle nut removes that mechanical lock, allowing critical components to work loose during operation and creating both a performance and safety concern.
