Thread Classifications
Threads can be classified by the following criteria:
Gender INTRODUCTION
Depending on the location of the surface, the thread may be external (cut on a rod)
or internal (cut into a hole).
External Thread Internal Thread
Designation
The threads are divided into fasteners or connection parts, running or kinematic (in a movable
connection) by main application. Often the fastening threads carry a second function - sealing the
threaded connection, ensuring its tightness.
