The Wacker Neuson Carriage Bolt is a genuine OEM fastener designed for HI750 and HI900 series indirect-fired air heaters. Sourced directly from Wacker Neuson, this carriage bolt meets the exact specifications of the original hardware installed at the factory. It is compatible across multiple HI750 and HI900 configurations, including surge brake, electric, and mobile variants. When a fastener fails or goes missing, replacing it with the correct OEM part ensures structural integrity and keeps your heater operating as intended.
Key Features
- Genuine OEM Fastener Grade — Manufactured to Wacker Neuson's exact material and dimensional spec, so thread engagement and clamping load match what the heater was built with.
- Drop-In Hardware Replacement — The domed head and square neck of a carriage bolt self-lock into position during installation, eliminating the need for a backup wrench on the bolt head.
- Broad HI-Series Compatibility — Fits HI750G, HI750GM, HI750GM HD, HI900DGM, and related indirect-fired heater configurations, covering both standard and surge-brake-equipped units.
- Structural Fastener Integrity — A correct-spec carriage bolt maintains the clamping force needed to keep panels, brackets, and assemblies secure under the vibration and heat cycles of continuous heater operation.
- Verified OEM Part Number — Part number 5000186720 is the factory-assigned reference for this bolt across all listed HI750 and HI900 configurations, ensuring you receive the right hardware every time.
A carriage bolt is a structural fastener used to clamp panels, housings, and mounting brackets together in equipment assemblies. Its rounded dome head and square shank beneath it bite into the mating material when tightened, preventing rotation without requiring tool access to the bolt head. On indirect-fired air heaters like the HI750 and HI900 series, fasteners like this one hold enclosure panels and internal components in place through repeated heating and cooling cycles. A missing, stripped, or incorrect-grade bolt can allow panels to shift or vibrate loose, compromising both the structural integrity of the unit and safe operation in the field.
