If you need a recommendation on torque range for the G4020 series fan from Mechatronics, Mechatronics has offered the following information:
To avoid cracking during assembly, it is essential to choose the correct torque value based on the screw type and size.
- If you are using a machine screw, the manufacturer recommends a torque of approximately 7 inch-lbs. This type of screw fully penetrates the fan frame.
- If you are using a self-threading screw, the recommended torque is around 5 inch-lbs. This type of screw taps into the fan frame’s material, and thread size plays a significant role in preventing damage.
The diameter of the self-threading screw threads is crucial. If the threads are too large, they may exert excessive pressure on the fan’s plastic frame, causing deflection and leading to cracks.
