Wacker Neuson 5200003876 Stud Bolt 8 X 106

The Wacker Neuson Stud Bolt 8 X 106 is a genuine OEM fastener designed for the GV3800 and GP3800A portable generators. Sourced directly from Wacker Neuson, this stud bolt meets the exact dimensional and material specifications set for these machines at the factory. It is a direct-fit replacement for the original hardware, ensuring a secure, properly torqued connection without any guesswork. If you are restoring a worn fastener position or completing a larger engine or housing service, part number keeps your repair on spec.

Key Features

• Genuine OEM Fastener Grade — manufactured to the precise thread pitch, shank diameter, and length specification (8 x 106) required for correct clamping load in these generator assemblies.
• Drop-In Hardware Replacement — matches the original stud bolt position exactly, threading into the same bore and accepting the same mating nut without rework or modification to surrounding components.
• Confirmed Fitment — verified for the Wacker Neuson GV3800 Value Portable Generator and GP3800A portable generator series.
• Structural Integrity Restored — a damaged, corroded, or under-torqued stud bolt can allow covers, flanges, or engine components to shift or leak; replacing it with the correct OEM part restores the designed clamping integrity.
• Fuel and Exhaust System Safety — stud bolts used in generator engine and exhaust flange applications are safety-critical fasteners; using the correct OEM part ensures joints remain sealed under heat cycling and vibration.

A stud bolt is a headless threaded fastener that threads permanently into a tapped bore on one end while a nut is applied to the exposed end to clamp a mating component in place. In portable generator applications, stud bolts are commonly used on engine flanges, exhaust connections, and structural covers where repeated disassembly is required — the fixed stud acts as an alignment guide and load-bearing anchor each time the joint is reassembled. When a stud bolt stretches, strips, or corrodes, the joint loses clamping force, which can lead to gasket failure, air or exhaust leaks, or loose components that vibrate free under load.
