The Wacker Neuson Hexagonal Head Cap Screw is a genuine OEM fastener designed for the HI750, HI900, and HI260 series indirect-fired air heaters. Sourced directly from Wacker Neuson, this OEM component matches the exact thread specification, head geometry, and material grade of the original hardware installed at the factory. The covers a broad range of HI-series configurations, including diesel, natural gas, propane, skid-mounted, and surge-brake variants across both the HI750 and HI900 families, as well as the HI260 oil-fired heater with tank. Keeping the correct fastener in place ensures structural integrity at critical connection points throughout the heater assembly.
Key Features
- Correct Thread Form and Head Geometry — Manufactured to OEM specification, this cap screw matches the original hex-head profile and thread engagement length, ensuring proper torque load and secure clamping across heater assembly joints.
- Genuine Wacker Neuson OEM Part — Supplied as a genuine OEM component under part number 5000182311, so you are installing the same fastener Wacker Neuson specifies for production and authorized service repairs.
- Broad HI-Series Compatibility — Fits a wide range of HI750, HI900, and HI260 indirect-fired air heater configurations, including diesel, natural gas, LP, skid-mounted, and surge-brake models.
- Structural Integrity at Critical Connection Points — A correctly torqued and properly sized cap screw maintains tight, vibration-resistant joints; a worn, stripped, or incorrect fastener risks loosening under sustained heater operation and thermal cycling.
- Fuel-System and Combustion Cabinet Safety — On indirect-fired heaters, fasteners secure panels and components in close proximity to the fuel system and heat exchanger. Using the correct OEM fastener helps maintain designed clamping force and keeps enclosures properly sealed during operation.
A hexagonal head cap screw is a threaded fastener with a six-sided head driven by a wrench or socket, designed to clamp two or more components together with a precise, controlled torque. On indirect-fired air heaters like the HI750, HI900, and HI260, cap screws are used throughout the frame, burner cabinet, heat exchanger mounts, and panel assemblies to hold structural and operational components in alignment under continuous heat and vibration. When a cap screw stretches, strips, or is replaced with an incorrect grade or thread pitch, clamping force is lost — which can allow panels to shift, create air leaks around the heat exchanger, or compromise the integrity of fuel-adjacent enclosures.
