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
