Dear all
I need to calculate the tightening torque for the metal thread insert in the plastic base material.
Is there any empherical relation avail?
M6 metal thread insert /10mm length in the plastic material.I asked to recommend the thread tightening torque..
I found relation referring one book (3.14*d^2)/2 *len*Shear stress of the plastic matl.
Shear stress recommendation 0.5 x Tensile strength(115n/mm^2-actual value got from testing) given in the same ref.book
I found that it is near to steel shear sress..i hope data given is wrong...
I think this torque is the maximum at which failure?
So i have to recommend less than this torque.
Result of the tightening torque found high...
I need suggestions & materials...
