Basics of screws that you may not know about
I don’t know how to manage torque.
Why do screws get loose?

I don’t even know where to start.

The screws will definitely come loose.  If you continue to rely on vague knowledge when designing, you may end up with serious accidents or complaints.

Why don’t you eliminate your worries at once at Saima’s TAK School?

I will mainly talk about what I have actually experienced.
“TAK SAIMA” is a super professional who has been traveling all over the world solving screw problems for over 30 years.
