WebbOverview. The Unified Thread Standard (UTS) defines a 60° thread form in Inch dimensions as described in the ASME B1.1 standard. It is the North American equivalent of the ISO metric thread system. The UTS serves as the leading standard for bolts, nuts, and a wide variety of other threaded fasteners used in the USA and Canada.
WebbScrew threads are not made perfectly sharp due to cost reasons in large series production. Besides a sufficiently large root diameter, they have to use a well-defined thread-root radius for high loading capacity regarding vibrational loads to avoid fatigue failures. mae west cartoonWebbThe following terms are associated with screw threads: • The thread pitch is the distance between corresponding points on adjacent threads. Measurements must be taken parallel to the thread axis. • The major diameter or outside diameter is the diameter over the crests of the thread, measured at right angles to the thread axis..
