Bomag Collar Nut | Part 05817153

The Bomag 05817153 Collar Nut is a genuine OEM replacement designed for a broad range of Bomag single drum rollers and tandem rollers, including the BW 213 D-5, BW 219 D-5, BW 226 DH-5, BW 177 D-5, BW 145 D-5, BW 211 D-5, and many additional BW-series and C 850 C models. Sourced directly from Bomag, this collar nut matches the original component in thread pitch, dimensional tolerances, and material grade — ensuring it seats and torques exactly as the factory intended. This is the same part number 05817153 used in Bomag's own service documentation, so you can order with confidence that it corresponds precisely to your machine's specification. Compatible machines also include BW 100, BW 120, and BW 135 tandem rollers, making this a widely applicable hardware component across multiple Bomag roller generations.

Key Features

• OEM-Matched Thread and Material Specification — manufactured to the same thread form, pitch, and hardness grade as the original Bomag collar nut, preventing stripping, cross-threading, or premature loosening under compaction loads.
• Drop-In Hardware Replacement — matches the original fastener geometry exactly, so this collar nut installs directly without chasing threads or modifying the mating component.
• Broad BW-Series Coverage — fits an extensive range of Bomag single drum rollers across the BW 145, BW 177, BW 211, BW 212, BW 213, BW 214, BW 215, BW 216, BW 218, BW 219, BW 220, and BW 226 series, as well as BW 100, BW 120, and BW 135 tandem rollers and the C 850 C single drum roller.
• Torque Retention Under Vibration — the collar nut design provides positive locking engagement, resisting the loosening forces generated by continuous vibratory compaction cycles that can work standard fasteners free over time.
• Correct Fastener for Critical Connections — using the correct OEM-specified collar nut on fastened assemblies in compaction equipment is essential; undersized or mismatched hardware can cause joint slippage and component damage during operation.

A collar nut is a threaded fastener with an integrated flange or collar that distributes clamping load across a wider bearing surface than a standard nut. This bearing surface helps prevent the fastener from pulling through or damaging softer mating materials, and the collar also acts as a built-in washer to maintain consistent clamp force across the joint. On vibratory rollers, where sustained high-frequency vibration is the normal working condition, using the correctly specified collar nut is critical — an improperly sized or worn fastener will allow joint movement that leads to component wear, misalignment, and eventual structural damage to the assembly it secures.
