If you screw a screw tight to a plate connecting to a base plate, it is
more-or-less in pure shear (no bending moment, unless the screw is
cantilevered).
What is the pullout/thread stripping process called? And actually, those
two processes would be distinct as well, correct?
Do they have proper names, or is pullout and thread stripping close
enough?
