The Wacker Neuson Hex Nylok Nut M14 is a genuine OEM component designed for the HI750, HI900, and HI1000 series mobile indirect fired air heaters. Sourced directly from Wacker Neuson, this fastener matches the original specification used on the production line, ensuring correct thread engagement and holding strength. Part number fits an extensive range of HI-series heater configurations including diesel, gas, and DGM variants across both electric brake and surge brake trailer setups. When you need a like-for-like replacement, this is the exact part the machine was built with.
Key Features
- Genuine OEM Nylok Retention: — The integrated nylon insert is matched to the original torque and vibration-resistance spec, so the nut stays locked under the thermal cycling and road vibration these heater units routinely experience.
- Correct M14 Thread Fit: — Threads directly onto existing M14 fastener points with no reworking of mating hardware, keeping disassembly and reassembly straightforward.
- Broad HI-Series Compatibility: — Confirmed fitment across HI750G, HI750D, HI750GM, HI750GM HD, HI900D, HI900DGM, HI1000, and HI1000DGM configurations, covering diesel, gas, and dual-fuel heater builds.
- Maintains Fastener Integrity Under Heat: — Designed to perform in the elevated-temperature environment of an indirect air heater, where standard nuts can back off over time and cause component loosening or structural movement.
- Direct OEM Sourcing: — Carries the Wacker Neuson part number 5000182266, giving you confidence that the part matches the original bill of materials for your specific heater model and serial range.
A hex nylok nut is a standard hex nut fitted with a nylon locking insert that grips the bolt threads and resists loosening caused by vibration, thermal expansion, and contraction. In mobile indirect air heaters like the HI-series units, fasteners are exposed to repeated heat cycles, trailer vibration during transport, and mechanical stress from blower and burner operation — conditions that can cause ordinary nuts to back off over time. A worn, damaged, or missing nylok nut can allow components to shift or separate, compromising both heater performance and safe operation of the unit.
