The Bomag 08158315 Castle Nut is a genuine OEM fastener designed for the BW 12 R pneumatic tyred roller. Sourced directly from Bomag, this castle nut delivers an exact match to the original hardware specification, ensuring a secure, properly torqued connection right out of the box. This component is engineered to fit the BW 12 R without any rework or improvisation, making it the straightforward choice when restoring or maintaining your machine's fastener integrity.
Key Features
- Genuine OEM Fastener Grade — manufactured to Bomag's original hardness and thread-pitch specification, so cotter-pin alignment and clamping load match the original design intent
- Direct Drop-In Replacement — threads and crown slots are dimensionally identical to the part it replaces, allowing installation straight from the box on the BW 12 R
- BW 12 R Compatibility — verified fitment for the BW 12 R pneumatic tyred roller, so there is no guesswork when ordering for this machine
- Secure Cotter-Pin Retention — the castle profile locks a cotter pin in place to prevent the nut from backing off under vibration and load cycles, keeping critical connections tight during compaction work
- Corrosion-Resistant Finish — surface treatment helps the nut resist rust and surface degradation in outdoor compaction environments, extending service intervals
A castle nut — also called a castellated nut — is a hex nut with a series of slots cut into one end that resemble the battlements of a castle tower. These slots accept a cotter pin or safety wire that passes through a corresponding hole in the bolt or shaft, mechanically locking the nut and preventing it from loosening due to vibration or dynamic loading. On a pneumatic tyred roller like the BW 12 R, castle nuts are typically used at wheel hubs, steering linkages, and axle assemblies where rotation and constant vibration are present. A worn, damaged, or missing castle nut can allow critical fastener connections to loosen over time, leading to excessive play, accelerated component wear, or loss of control in severe cases.
