Key Features
- Genuine OEM Thread and Port Integrity — manufactured to Bomag's original dimensions, this hollow screw delivers the precise thread engagement and internal bore geometry required for a leak-free, secure connection in hydraulic or fluid-circuit applications.
- Direct Drop-In Replacement — this part installs directly in place of the original with no rework or adaptation, matching the original mounting configuration on Bomag single drum rollers.
- Broad Single Drum Roller Coverage — confirmed fitment across BW 177, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, BW 225, and C 850 C single drum rollers, including D, DH, PDH, and DHC variants in both standard and USA configurations.
- Fluid System Reliability — a correctly seated hollow screw maintains proper flow path alignment and sealing in the circuit it serves; a worn, cross-threaded, or incorrect screw risks fluid leaks, pressure loss, and unplanned service interruptions on the roller.
A hollow screw is a threaded fastener with a drilled-through center bore that allows fluid — typically oil or hydraulic fluid — to pass through a connection point while the screw itself clamps the fitting or line securely in place. It is commonly found in hydraulic and lubrication circuits where a banjo-style fitting must be sealed against a port or housing. When this screw is damaged, incorrectly torqued, or replaced with the wrong specification, the result is fluid seepage or outright leakage at the joint, which can compromise hydraulic pressure, contaminate surrounding components, and lead to accelerated wear elsewhere in the system. Using the correct OEM-spec hollow screw ensures the internal bore diameter and thread pitch match the original design, maintaining a reliable, sealed connection throughout the service life of the roller.
