The Wacker Neuson is a genuine OEM Hexagonal Head Cap Screw designed for the E1250S and E1250P hydronic surface heaters and the HSH380S hydronic surface heater series. As a direct OEM replacement, this fastener is manufactured to the exact thread profile, head geometry, and material grade specified by Wacker Neuson for these machines — ensuring a secure, rattle-free connection wherever it is installed. This screw fits across multiple E1250 and HSH380S configurations, including LP/NG, Diesel, Standard, and Premium variants, as well as generator-equipped HSH380S models. Keeping the correct hardware on hand helps you complete service or assembly work without delays or improvised substitutions.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to Wacker Neuson's specified thread form, head dimensions, and tensile grade, so clamping force and torque ratings stay within design parameters.
- Drop-In Replacement — Matches the original screw's thread pitch, shank length, and hex drive size for straightforward installation without re-tapping or rework.
- Broad E1250 and HSH380S Coverage — Confirmed fitment across E1250S (Standard LP/NG), E1250P (Premium LP/NG and Diesel), HSH380S (Natural Gas/Propane and Diesel with Generator) configurations.
- Structural Reliability in Heated Environments — Hydronic heater assemblies operate under sustained heat and vibration; using the correct-grade cap screw prevents joint loosening and housing stress over extended run cycles.
- Genuine Wacker Neuson Part — Supplied under part number 5000157970 directly within the Wacker Neuson OEM parts program, so you can be confident you are installing the exact component the machine was built with.
A hexagonal head cap screw is a threaded fastener used to clamp or secure two or more components together within an assembly. In hydronic surface heaters like the E1250 and HSH380S series, cap screws are used throughout the frame, burner, and fluid circuit assemblies to maintain structural integrity and fluid-tight connections under continuous thermal cycling. When a cap screw is stripped, corroded, or missing, the joint it secures can loosen, leading to misalignment, vibration damage, or — in fuel and fluid circuit locations — potential leaks that affect heater performance and safety.
