The Wacker Neuson Bolt With Washer is a genuine OEM fastener designed for the GP2500A, GP3800A, GP3800, and GP4000 series portable generators. As a factory-sourced component, it matches the exact dimensions, thread pitch, and integrated washer profile specified for these units — ensuring correct clamping load and a flush, secure fit without improvisation. This bolt with washer is used across a wide range of GP-series configurations including standard portable, premium, wheel kit, EPA-compliant, and CSA-certified variants, making it a high-demand service item for technicians maintaining multiple generator models in a fleet setting.
Key Features
- OEM Thread and Dimensional Accuracy — Sourced directly from Wacker Neuson, this bolt carries the exact thread specification and integrated washer geometry called out in the original assembly, preventing uneven clamping or fastener fatigue.
- Drop-In Installation — Matches the original bolt position and torque spec on GP-series generators, so it threads in and seats without reworking adjacent hardware.
- Broad GP-Series Compatibility — Confirmed for GP2500A, GP3800A, GP3800, and GP4000 generators across standard, premium, wheel kit, EPA, and CSA configurations.
- Structural Integrity Where It Counts — A correctly torqued bolt with washer maintains panel, component, or frame alignment on the generator; a stripped or incorrect fastener can allow vibration-induced movement that damages surrounding parts over time.
- Genuine OEM Part — Carries Wacker Neuson part number 5000162512, so you can cross-reference against the original parts diagram with confidence before ordering.
A bolt with washer is a combined fastener that integrates a washer element directly with the bolt, distributing clamping force over a wider surface area and reducing the risk of pull-through or surface damage on the mating component. On portable generators like the GP series, fasteners of this type are commonly used to secure covers, frames, handles, and mounting brackets that must withstand continuous engine vibration during operation. When a bolt stretches, corrodes, or the washer face becomes deformed, it can no longer maintain proper clamping load, leading to loose assemblies, increased vibration transmission, and potential damage to the components it secures.
