The Wacker Neuson Bolt 1/4-20 X 2-1/2 is a genuine OEM fastener designed for the G-Series portable generator lineup, spanning the G25, G50, G70, G85, G150, G180, G230, G240, and G320 mobile generator families. Sourced directly from Wacker Neuson, this bolt is manufactured to the exact thread specification and dimensional tolerances required for proper installation and secure clamping force on these units. Whether you are servicing a standard skid-mounted unit, a cold-weather configuration, or a custom T4 emissions variant, part number is the correct replacement fastener. Verified fitment extends across an extensive range of G-Series configurations, including extended run tank, Tier 3, and Tier 4 Final models, as well as select HI-Series indirect-fired heater and MGT generator trailer applications.

Key Features

  • Correct Thread Form and Grip Length — 1/4-20 UNC threading and a 2-1/2 inch grip length match the original fastener specification exactly, ensuring proper torque retention without stretching or bottoming out.
  • Genuine OEM Construction — Manufactured to Wacker Neuson's material grade requirements, delivering the hardness and tensile strength needed to maintain joint integrity under generator vibration and thermal cycling.
  • Broad G-Series Compatibility — Fits a wide range of G25, G50, G70, G85, G150, G180, G230, G240, and G320 mobile generator configurations, including standard, cold-weather, custom, extended run, and Tier 4 Final variants.
  • Maintains Structural Clamping Force — A worn or incorrect-length bolt compromises panel, bracket, or enclosure retention; replacing with the OEM fastener restores the designed clamping load and prevents component loosening during operation.
  • Drop-In Installation — Matches the original bolt's head size, thread pitch, and shank length, allowing straightforward swap-out with standard hand tools during routine service or repair.

A fastener of this type provides the mechanical clamping force that holds structural panels, brackets, enclosures, or internal assemblies together in a generator set. On mobile generators subject to transport vibration and continuous engine operation, maintaining the correct bolt specification — including thread pitch, diameter, and length — is critical to keeping joints secure and preventing component movement that can lead to misalignment or accelerated wear on adjacent parts. Using the correct OEM replacement ensures the fastener seats and torques as originally intended, without the risk of thread mismatch or inadequate clamp load associated with substitute hardware.
