Maximum tightening torque for metric self tapping screws
Hi all,
Can someone help me to find out the maximum tightening torque for metric self tapping screws.
Actually I am using M3, M4 and M5 ST screws for fixing the plastic parts together.
Now I am going to prepare assembly guideline document for each SKU, So there I need to mention the tightening torque of each screw which is used in assembly. But I am not getting the direct values of torque.
I got the analytical calculations to find out the require tightening torque when clamping force is known but I am interested in maximum tightening torque which can be applied on screw.
Have a great time...
Thanks,
