The Wacker Neuson Stud Bolt is a genuine OEM stud bolt designed for the RD24-100, RD27-120, RD28-120, and related tandem roller series, including standard, C, O, DPF, and electric variants. As a direct factory replacement, this part is manufactured to the same specifications as the original, ensuring a drop-in fit with no guesswork at the service bay. It covers an extensive range of Wacker Neuson tandem rollers across multiple production generations, making it a reliable go-to when servicing these machines. Confirm your model number before ordering to ensure this part matches your specific roller configuration.
Key Features
- Genuine OEM Threading Integrity — Manufactured to exact thread pitch and shank dimensions, so the bolt seats and torques correctly without risk of cross-threading or improper clamping force.
- Direct Factory Replacement — Drops straight into the original mounting position on your tandem roller, matching the hole pattern and engagement length of the factory-installed hardware.
- Broad Tandem Roller Coverage — Fits RD24-100, RD27-120, RD28-120, and their C, O, DPF, and electric (e) variants across multiple production generations, covering both US and international market machines.
- Structural Connection You Can Trust — A correctly fitted stud bolt maintains the clamping integrity of critical assemblies on your roller; a worn, stretched, or incorrect bolt risks loosening under compaction vibration loads.
- Sourced Direct from Wacker Neuson — Supplied as a genuine Wacker Neuson OEM part, backed by the manufacturer's parts program for verified authenticity.
A stud bolt is a fully threaded or partially threaded fastener used to clamp two or more components together within a machine assembly. Unlike a standard bolt, a stud screws permanently into one component, with a nut then driven onto the exposed end to secure the mating part — a design that allows repeated assembly and disassembly without wearing the threaded bore of the housing. On a tandem roller like the Wacker Neuson RD series, stud bolts appear in high-vibration assemblies where consistent clamping force is critical. A damaged or incorrectly specified stud bolt can lead to loosening, component misalignment, or accelerated wear in the surrounding assembly, so replacing it with the correct OEM part is the straightforward way to restore the joint to its original holding strength.
