The Wacker Neuson Lock Screw G 1/4" is a genuine OEM component designed for the TH627 hydronic surface heater. Sourced directly from Wacker Neuson, this lock screw is an exact match to the original hardware specified for the TH627 — ensuring a proper, secure fit without guesswork. If your current screw is stripped, damaged, or missing, replacing it with the correct OEM part keeps the system operating as intended.
Key Features
- Genuine OEM Thread Specification: — Manufactured to the exact G 1/4" thread standard, matching the original screw spec for the TH627 without adaptation.
- Secure Locking Function: — Maintains clamping integrity in the application port or fitting it secures, preventing loosening under vibration or thermal cycling common in heating equipment.
- Direct Fitment for TH627: — Listed as a confirmed OEM replacement for the TH627 hydronic surface heater, so you can order with confidence in part compatibility.
- Correct Material Grade: — Produced to OEM hardness and corrosion-resistance standards appropriate for use in a hydronic heating circuit environment.
- System Integrity: — A correctly fitted lock screw prevents fluid leaks or pressure loss at the connection point it secures — a small part with a direct impact on heater performance and safety.
A lock screw with a G 1/4" thread is a precision-threaded fastener used to seal or secure a port, fitting, or adjustment point within a fluid or pneumatic circuit. In a hydronic surface heater like the TH627, these screws are commonly used to plug unused ports or lock adjustable components in position, preventing fluid bypass or unintended movement. A damaged, cross-threaded, or missing lock screw can allow fluid leakage or pressure loss, directly affecting the heater's ability to maintain consistent output.
