The Wacker Neuson Hex Keps Nut M6 x 1 SS is a genuine OEM fastener designed for the HI and HSH series indirect-fired air heaters and hydronic surface heaters. As a stainless steel keps nut with an M6 x 1 thread, it delivers corrosion resistance and secure self-locking retention in demanding jobsite heating environments. This genuine OEM part is sourced directly from Wacker Neuson, ensuring the correct thread pitch, material grade, and locking washer engagement for a verified fit. Confirmed fitment spans the HI260, HI750, HI900, HI1000, HIF600, and HSH350 series machines.
Key Features
- Stainless Steel Construction — The SS material grade resists corrosion and oxidation, critical for fasteners exposed to moisture, heat cycling, and outdoor conditions common on heating equipment.
- Integrated Keps Locking Washer — The built-in free-spinning lock washer engages on installation to prevent loosening from vibration, eliminating the need for a separate locking element at that fastener point.
- M6 x 1 Thread Specification — Standard metric coarse thread pitch ensures direct engagement with existing threaded bosses and hardware on Wacker Neuson HI and HSH series heaters without rethreading or modification.
- Wide Series Compatibility — Fits HI260, HI750, HI900, HI1000, HIF600, and HSH350 series indirect-fired air heaters and hydronic surface heaters, covering both gas and diesel configurations.
- Genuine OEM Part — Supplied by Wacker Neuson as original equipment, matching the exact thread engagement and locking torque characteristics specified for these heater assemblies.
A keps nut — also called a K-lock or keps lock nut — is a standard hex nut with a free-spinning external tooth lock washer permanently attached to its bearing face. When tightened, the serrated washer bites into the mating surface, creating mechanical resistance to loosening caused by vibration or thermal expansion and contraction cycles. On indirect-fired air heaters and hydronic surface heaters like the Wacker Neuson HI and HSH series, fastener integrity is critical throughout the burner, heat exchanger, and housing assemblies; a loose or corroded nut can compromise panel retention, airflow sealing, or component mounting. Replacing worn or damaged fasteners with the correct grade and thread specification — as with the 5000177095 — keeps the assembly properly torqued and structurally sound through repeated heating and cooling cycles.
