I see some M5 screws are short, maybe only 6mm long. Some M5 screws are 30 mm long.
If I simplify the calculation and use equation "Friction = friction coefficient x normal force"
Assume the bolt is in tension. The friction between the bolt and the tap hole should not change if I use a longer bolt, right?
