The thread angle 60 degrees

Due to the use:

  • Thread coupling
  • Leadscrew

Because of the shape:

  • Metric
  • Buttress
  • Symmetrical trapezoidal thread
  • Rectangular thread
  • Thread round
  • Conical thread
  • Thread rolling
  • Triangular thread
  • Threaded to timber
  • Cylindrical thread
  • Bicycle thread

Due to the location:

  • External thread – GZ
  • Internal thread – GW

Because of the fold:

  • Thread single
  • Threads double (multiple)

Because of stroke:

  • Normal thread
  • Fine thread
  • Coarse thread

Because of the way of twisting:

  • Right-hand thread
  • Left-hand thread
