Key Features
- Genuine OEM Hardware Grade — manufactured to Bomag's exact material and thread specifications, ensuring the domed cap nut seats and torques correctly without galling or stripping
- Direct-Fit Replacement — matches the original fastener profile, thread pitch, and dome geometry for straightforward installation with standard tooling
- Broad Single Drum Roller Coverage — fits BW 145, BW 177, BW 211, BW 212, BW 213, BW 214, BW 215, BW 216, BW 218, BW 219, and BW 226 single drum rollers across multiple generation variants, including D-4, D-5, D-40, DH-4, DH-5, and EU-Flex configurations
- Protective Domed Profile — the closed dome shields the exposed thread end from corrosion, impact damage, and contamination, extending the service life of the fastened assembly in harsh compaction environments
- Exact Part Number Match — referencing part number 58003844 when ordering eliminates substitution errors and ensures the correct fastener is installed the first time
A domed cap nut is a closed-end fastener that threads onto a bolt or stud, securing an assembly while simultaneously covering and protecting the protruding thread from moisture, dirt, and mechanical damage. On heavy single drum rollers operating in soil compaction environments, exposed fasteners are constantly subjected to vibration, mud, and impact — conditions that accelerate corrosion and thread degradation. When a domed cap nut becomes stripped, cracked, or seized, it can compromise the integrity of the joint it secures and make future servicing significantly more difficult; replacing it promptly with the correct OEM part maintains the clamping force and protective function the original design intended.
