Thermocouple alloy and junction selection
K Type Thermocouple M4 Screw: Match thermocouple type, polarity and extension cable to the controller input. Select protection-tube material and grounded or ungrounded junction for the atmosphere, electrical noise and response required.
Define insertion depth and the mechanical support at the process connection. A temperature stated in a product name needs confirmation for the complete probe assembly, cable transition and continuous duty.
For K Type Thermocouple M4 Screw, send the controller input, required measurement range, accuracy, probe drawing and cable or connector details. Ask for the agreed sensor designation and inspection requirements on the quotation.
Application and reference configuration
Industrial temperature monitoring and furnace control. The final suitability of K Type Thermocouple M4 Screw depends on the assembled equipment and agreed operating conditions.
Archived figures below describe reference options or a product series. Confirm the exact model specification in the quotation.

Description
Product Description
OEM ODM industrial M8 rtd E J K type high temperature sensor thermocouple m6 screw
An M3/M4 screw thermocouple is a compact temperature sensor with either an M3 (3mm) or M4 (4mm) threaded screw for easy mounting in tight spaces or small equipment. These are commonly used in electronics, industrial automation, and precision instruments where secure attachment and fast thermal response are needed.
Key Features & Differences
| Feature | M3 Screw Thermocouple | M4 Screw Thermocouple |
|---|---|---|
| Thread Size | 3mm diameter | 4mm diameter |
| Strength | Less robust, for low-vibration applications | More durable, better for industrial use |
| Response Time | Faster (smaller mass) | Slightly slower (larger mass) |
| Common Uses | PCBs, small electronics, drones, lab tools | Motors, extruders, CNC machines, HVAC |
| Max Temp | Depends on thermocouple type (e.g., Type K: up to 1250°C) |
