The Wacker Neuson Bolt is a genuine OEM fastener designed for the HI750 and HI900 series indirect-fired air heaters. Sourced directly from Wacker Neuson, this bolt matches the original part in grade, thread pitch, and dimensions — ensuring a correct, secure fit without guesswork. It is confirmed compatible across multiple HI750 and HI900 configurations, including standard, DGM, surge brake, and heavy-duty mobile variants. When you need to restore a fastener to spec, this is the part to reach for.
Key Features
- Genuine OEM Grade Fastener — Manufactured to Wacker Neuson's original material and thread specification, so you get the correct tensile strength and corrosion resistance for heater service environments.
- Direct Drop-In Replacement — Threads, head size, and length match the original bolt, allowing straightforward installation without chasing threads or sourcing additional hardware.
- Broad HI Series Fitment — Compatible with HI750G, HI750GM, HI750GM HD Mobile, HI900DGM, and related indirect-fired air heater models, covering standard and cold-weather surge brake configurations.
- Structural Integrity Restored — A missing or damaged bolt in a heater assembly can allow panels, brackets, or components to shift under vibration; replacing it promptly keeps critical assemblies properly secured.
- Fuel System and Heat Exchanger Safety — Fasteners securing fuel-side or combustion-side components must meet original torque and grade specs; using a genuine OEM bolt ensures no compromise on those critical joints.
A bolt in an indirect-fired air heater serves as the primary fastening element holding structural panels, brackets, burner assemblies, and heat exchanger components in their correct positions. Because indirect heaters operate under continuous vibration, thermal cycling, and high output conditions, fasteners are subject to significant stress over time. A bolt that is stripped, corroded, or missing can allow components to shift, creating misalignment, air leaks, or unsafe operating conditions — making timely replacement with a correctly graded OEM fastener the straightforward fix.
