The Bomag 05939123 Lock Bolt is a genuine OEM replacement designed for the BW 120 AD tandem roller, BW 213 D single drum roller, and a wide range of Bomag cold milling machines including the BM 500/15, BM 600/15, BM 1000/35, BM 1200/35, BM 1300/35, BM 2000/75, BM 2200/75, and BM 2500/75. Sourced directly from Bomag, this lock bolt matches the original component specification for a drop-in installation with no guesswork. Coverage extends across multiple generation variants including BM 500/15-2, BM 600/15-2, BM 600/15 EU-Flex T4i, BM 1200/35 T4f, BM 1300/35 T4f, BM 500/15 Stage V, and BM 600/15 Stage V, making part number 05939123 a reliable choice across a broad fleet of Bomag equipment.
Key Features
- Genuine OEM Locking Integrity — manufactured by Bomag to the exact torque retention and thread specification of the original, so the fastener holds under the vibration and load cycles these machines generate
- Direct Bolt-In Replacement — matches the original thread pitch, shank dimensions, and head geometry for straightforward installation against existing hardware
- Wide Fleet Coverage — fits the BW 120 AD tandem roller, BW 213 D single drum roller, and BM-series cold milling machines spanning the BM 500/15 through BM 2500/75, including T4f, T4i, Stage V, and second-generation variants
- Vibration-Resistant Locking Design — the lock feature prevents loosening during continuous machine operation, maintaining the integrity of the assembly it secures
- Verified Part Number Traceability — ordering by Bomag part number 05939123 confirms you receive the correct fastener for your specific machine variant, eliminating substitution errors at the counter
A lock bolt is a fastener engineered to resist self-loosening under sustained vibration and dynamic loading — conditions that standard bolts can struggle to maintain over time. In milling machines and rollers, fasteners in high-vibration zones can back out gradually, causing component misalignment, accelerated wear, or loss of structural integrity in the assembly they secure. Replacing a worn or compromised lock bolt with the correct Bomag OEM component restores the clamping force and locking action the original design relies on, keeping the surrounding assembly properly held through demanding compaction and milling cycles.
