The Wacker Neuson is a genuine OEM Screw 3/8 - 16 UNC x 1 1/4 VZD designed for the TH627 indirect-fired air heater. Sourced directly from Wacker Neuson, this fastener is produced to the exact thread form, grade, and zinc-dichromate (VZD) surface finish specified for the application. Having the correct OEM hardware on hand keeps your heater assembly together and operating as designed. Verify part number against your TH627 parts list before ordering to confirm this is the right screw for your application.
Key Features
- Correct Thread Specification: — 3/8 - 16 UNC thread form matches the original fastener specification exactly, so the screw seats and torques correctly without risk of cross-threading or stripping.
- Zinc-Dichromate (VZD) Finish: — The VZD coating provides corrosion resistance suited to the demanding environment of a diesel-fired heater, helping the fastener hold up against heat cycling and moisture exposure.
- Genuine OEM Part: — Manufactured to Wacker Neuson's own material and dimensional standards, ensuring consistent tensile strength and fit with the hardware it secures.
- Direct TH627 Fitment: — Confirmed for the TH627 indirect-fired air heater; cross-reference part number 1000451574 with your machine's spare parts list (418-02) to verify the correct fastener position.
- Structural Integrity of the Heater Assembly: — A worn, stripped, or incorrect fastener in a heater assembly can lead to loose components, vibration damage, or compromised housing integrity. Using the correct screw maintains a secure, properly torqued assembly.
A fastener like the 3/8 - 16 UNC x 1 1/4 VZD screw serves as a structural anchor within the heater assembly, clamping components together at the specified clamp load for the joint. The VZD (zinc-dichromate) coating is not purely cosmetic — it protects the fastener's surface from oxidation and corrosion that could otherwise seize the screw or cause it to lose clamping force over time. When a fastener fails, stretches, or is replaced with an incorrect thread pitch or length, it can result in loose panels, misaligned components, or accelerated wear on the surrounding hardware, making correct part selection essential at every service interval.
