The Bomag 31780545 Hollow Screw is a genuine OEM fastener designed for a wide range of Bomag tandem rollers, single drum rollers, and pneumatic tyred rollers. Sourced directly from Bomag, this hollow screw delivers the exact dimensions and thread specification required for a correct, secure installation with no guesswork. Confirmed fitment covers models including the BW 184 AD, BW 184 AD-2, BW 180 AD, BW 213 D-3, BW 213 DH-3 USA, BW 213 PDH-3, BW 213 PDH-3 USA, BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 211-40, BW 24 R, C 850 C, and C 560 B, among others. Choosing a genuine OEM component ensures the screw matches the original material grade and geometry that Bomag engineered into these machines.
Key Features
- OEM-Matched Thread and Bore Specification — manufactured to the exact thread pitch, outer diameter, and internal bore dimensions Bomag specifies, ensuring a fluid-tight or mechanically sound connection in the intended port or passage.
- Direct-Fit Replacement — installs in place of the original hardware using standard tooling, with no modification to the host component or surrounding assembly.
- Broad Roller Compatibility — fits Bomag tandem rollers including the BW 184 AD and BW 180 AD, single drum rollers including the BW 213 D-3 and BW 177 DH-3 series, and pneumatic tyred rollers including the BW 24 R and C 560 B.
- Genuine Bomag OEM Quality — produced to the same material and hardness standards as the original, guarding against thread galling, cross-threading, or premature failure under vibration and load cycles common to compaction equipment.
- Leak and Failure Prevention — a hollow screw that is worn, cross-threaded, or dimensionally incorrect can cause fluid loss or fastener failure; replacing it with the correct OEM part restores the integrity of the connection and keeps the system operating as intended.
A hollow screw is a threaded fastener with a machined internal bore that allows fluid — typically hydraulic oil, coolant, or fuel — to pass through its center while still clamping two components together. It is commonly used at banjo fittings, where it secures a banjo bolt connection and simultaneously provides a sealed fluid pathway between hoses or lines and their host component. When a hollow screw becomes damaged, corroded, or stripped, the joint can weep fluid or lose clamping force entirely, leading to system pressure loss or contamination. Replacing it promptly with the correct OEM part restores the sealed connection and maintains the performance of the hydraulic or fluid circuit it serves.
