The fundamental profile of all UTS threads is similar to that of all ISO metric screw threads. Only the normally used values for Dmaj and P differ in between The 2 expectations. The insignificant diameter is the reduce Extraordinary diameter of the thread.

They may be utilised on apps in which a washer is necessary to distribute the load. They can be found in apps that demand more powerful fixings and therefore are tightened/loosened by making use of a spanner/wrench.
