摘要

the collar and the thread bottom of the under-head threading have a tightening of at least 0.01 mm if the collar is made from metal or ceramic and at least 0.05 mm if the collar is made from polymer, so as to create a hard spot toward the end of the placement of the screw, said hard spot remaining after the screw has been placed.
