The Wacker Neuson Hex Nut 10-32 Nylock Thin Zinc is a genuine OEM fastener designed for HI260 and HI1000 series indirect air heaters. Sourced directly from Wacker Neuson, this part meets the exact specifications used in original production, ensuring a drop-in replacement with no guesswork. It is confirmed compatible across the full HI260 and HI1000 lineup, including gas, diesel, and DGM electric and surge brake variants.
Key Features
- Genuine OEM Nylon Insert Retention — The nylon locking insert is formed to the same torque-retention spec as the original, maintaining consistent clamping force under vibration and heat cycling common to heater operation.
- Zinc Plating for Corrosion Resistance — Zinc finish provides a protective barrier suited to the thermal and moisture exposure found in indirect air heater environments.
- Thin Profile for Tight Clearances — The thin hex design allows installation in space-restricted mounting locations where a standard-height nut would not seat properly.
- Broad HI Series Compatibility — Fits HI260 oil heater with tank and all HI1000 indirect air heater configurations, including gas, diesel, diesel with tank, and HI1000DGM models.
- Direct OEM Replacement — Part number 5200022440 cross-references directly to the original fastener position, threading onto existing 10-32 hardware without any modification to surrounding components.
A nylock hex nut uses a nylon insert at the top of the nut that grips the bolt threads when tightened, creating resistance to loosening caused by vibration and repeated thermal expansion and contraction. In indirect air heaters like the HI260 and HI1000, fasteners are subjected to consistent heat cycling and mechanical vibration during operation, making locking retention critical to maintaining secure assemblies. A worn or absent nylock insert allows fasteners to back out over time, which can lead to loose panels, misaligned components, or more significant mechanical failures if left unaddressed.
