The Wacker Neuson Cable Fastener Nut is a genuine OEM component designed for HI, HD, and HDR series indirect and direct fired heaters. As a factory-sourced part, it is manufactured to the exact specifications used in original production, ensuring a correct, consistent installation every time. This nut is compatible with a broad range of Wacker Neuson heater models including the HI 400HD G, HI 300HD D, HI 110HD D, HI 200D, HDR 155, HDR 115, HDR 45, HD 50, HD 70, HI 35, HI 90, HI 90HD, HI 120, and HI 120HD. When you need an accurate, like-for-like replacement, sourcing a genuine OEM part eliminates guesswork and keeps your heater operating as intended.
Key Features
- Genuine OEM Fastener Integrity — Manufactured by Wacker Neuson to the same thread form, torque rating, and material specification as the original, so the cable retention hold is never compromised.
- Direct Drop-In Replacement — Matches the original mounting thread and seating geometry exactly, so installation requires no reworking of the cable assembly or surrounding hardware.
- Broad Heater Series Coverage — Fits HI, HD, and HDR series units spanning indirect air and direct fired radiant heaters, covering diesel and gas configurations across multiple output ratings.
- Secure Cable Retention — A correctly seated cable fastener nut keeps control and fuel-system cables firmly anchored; a loose or damaged nut can allow cable movement that disrupts heater operation or causes premature cable wear.
- Verified Part Number Fit — Cross-reference part number 5200021239 against your machine's serial plate or parts manual to confirm compatibility before ordering.
A cable fastener nut secures cables — such as control cables or fuel-line cables — to fixed anchor points within the heater assembly, preventing unwanted movement, vibration-induced wear, and misalignment during operation. Keeping the cable correctly positioned is essential for consistent heater control response and safe, uninterrupted fuel delivery. When this nut is worn, stripped, or missing, cables can shift out of position, leading to erratic heater behavior or accelerated wear on the cable itself.
