Thread angle information


Diagram of a thread angle

In mechanical engineering, the thread angle of a screw is the included angle between the thread flanks, measured in a plane containing the thread axis.[1] This is a defining factor for the shape of a screw thread. Standard values include:

Name Code Angle Profile Standards
Most V-threads (including ISO, NPT and UTS) M 60° DIN 13 / ISO ? / ASME/ANSI ?
Whitworth threads W 55° DIN 49301 / BS ?
