Wacker Neuson 5100078217 Stud M8x50 8.8 Zinc Coated

The Wacker Neuson Stud M8x50 8.8 Zinc Coated is a genuine OEM fastener designed for the G25 generator series. Sourced directly from Wacker Neuson, this stud matches the exact thread pitch, length, and strength grade called out in the original build specification, ensuring a drop-in replacement with no guesswork. Whether you are completing a scheduled service or replacing a damaged fastener after a repair, part number restores the joint to its original clamping integrity. Confirm your model number against the fitment data before ordering to be certain this is the correct stud for your machine.

Key Features

• Correct Strength Grade for the Application — Grade 8.8 carbon steel construction delivers the thread tensile strength required for structural and mechanical joint integrity on the G25.
• Zinc Coating for Corrosion Resistance — The zinc coating (ZNC finish) protects the stud threads against rust and oxidation, helping the fastener release cleanly during future service intervals.
• M8x50 Thread and Length Match — Exact M8 thread form and 50 mm shank length means the stud seats and torques correctly without shimming, modification, or thread chasing.
• Genuine OEM Part — Manufactured to Wacker Neuson standards and supplied under OEM part number 5100078217, so the grade marking, thread tolerance, and finish are exactly what the machine was built with.
• Verified Fitment for G25 Generators — Cross-referenced to the G25 (5100050024) generator, giving you confidence you are installing the right hardware the first time.

A stud is a fully threaded fastener that anchors components together by threading into a tapped bore on one end and accepting a nut on the exposed end, creating a strong, reusable clamping joint. Unlike a bolt, a stud stays fixed in the base component, allowing the mating part to be removed and reinstalled repeatedly without disturbing the threaded seat. Using the correct grade and length is critical — an undersized or lower-grade stud can stretch, strip, or fail under load, leading to loose assemblies, vibration damage, or component separation during operation.
