Wacker Neuson 5000167692 Hex Nut 5/16-18

The Wacker Neuson is a genuine OEM Hex Nut 5/16-18 designed for a wide range of Wacker Neuson hydronic surface heaters, ground heaters, indirect air heaters, pump packs, and hose handling systems. This fastener is sourced directly from Wacker Neuson and meets the exact material and dimensional specifications used in original production. Confirmed fitment spans the E3000, E2200, E1100, E5000, HSH350, HSH650, HSH700, HI900DGM, HI1000, HI1000DGM, HI260, and Pureheat series, as well as DPP33, DPP8.8, SPP4.4, and BP45 pump and booster pack models. When you need an exact-match replacement fastener for your heating or fluid-circulation equipment, part number is the correct genuine OEM choice.

Key Features

• Genuine OEM Material Grade — Manufactured to the precise thread class and tensile specification Wacker Neuson uses in production, ensuring the nut seats and torques correctly without stripping or backing out under vibration and thermal cycling.
• Standard 5/16-18 UNC Thread — The unified coarse thread pattern threads directly onto existing studs and bolts throughout the heater and pump assemblies, requiring no thread chasing or rework on installation.
• Broad Cross-Series Compatibility — A single part number covers hydronic surface heaters, ground heaters, indirect air heaters, pump packs, and hose handling systems across the E-series, HSH, HI, Pureheat, and DPP/SPP/BP families.
• Thermal and Vibration Resistance — Used in heating equipment that operates through extended cold-weather cycles; the correct fastener grade prevents loosening caused by repeated heat expansion and contraction that can work a sub-spec nut free over time.
• Critical Structural Integrity — Fasteners in heating and fluid-circulation equipment secure panels, burner assemblies, and plumbing brackets; a failed or incorrect nut can allow components to shift, creating fuel, fluid, or exhaust hazards in enclosed work environments.

A hex nut is a standard threaded fastener used to clamp and secure components together on a matching bolt or stud. In heating and pump equipment, hex nuts appear throughout the frame, burner housing, fluid manifold, and access panel assemblies, where they must maintain clamp load through repeated heating and cooling cycles as well as the vibration generated during operation and transport. A nut that is the wrong thread pitch, undersized, or made from a lower-grade material can strip, seize, or loosen prematurely, allowing critical components to shift out of alignment or creating gaps in sealed enclosures where exhaust gases or pressurized fluids are present.
