Wacker Neuson 5000107543 Stud M8X20 10.9

The Wacker Neuson Stud M8X20 10.9 is a genuine OEM fastener designed for the RD25 hydrostatic double drum vibratory roller. As a grade 10.9 metric stud, this component is manufactured to meet exact tensile and torque specifications required in critical bolted joints on the RD25. Sourced directly through Wacker Neuson's OEM supply chain, part number ensures a correct, specification-matched replacement every time. Verified fitment covers RD25 roller configurations, making this the straight swap for worn, damaged, or missing studs on these machines.

Key Features

• Grade 10.9 Tensile Strength — High-strength metric fastener rated to grade 10.9, providing the clamping force and shear resistance demanded in load-bearing and vibration-exposed assemblies on compaction equipment.
• Genuine OEM Specification — Produced to Wacker Neuson's exact thread pitch, length, and material standards, ensuring the stud seats and torques correctly without under- or over-spec concerns.
• Direct Fitment for RD25 Tandem Rollers — Confirmed compatibility with RD25 hydrostatic double drum vibratory rollers, covering both recorded machine configurations for this part.
• Vibration-Resistant Fastening — On vibratory rollers, fastener grade directly affects joint integrity under continuous oscillation; a correct-grade stud prevents joint loosening and structural movement between cycles.
• Safety-Critical Hardware Compliance — Using the correct grade and dimensional specification for structural studs on compaction rollers is essential — substituting incorrect-grade fasteners in these joints can compromise machine integrity and operator safety.

A stud is a fully threaded or partially threaded fastener used to create a fixed threaded post into which a nut is then tightened, forming a secure bolted joint without the need for a bolt head. On vibratory compaction equipment like the RD25 tandem roller, studs are used in assemblies that experience repeated mechanical stress and vibration — making grade classification critical. When a stud fails, stretches, or strips, the joint it secures can loosen or separate, leading to misalignment, component damage, or unsafe machine operation. Replacing a failed stud with the correct OEM-grade equivalent restores the original clamping integrity of the joint.
