Lead Screw Thread Types

1.T ISO Trapezoidal Thread Din103

For transmission and position adjustment,widely used in the mechanical industry.

2.H High-helix Screws

A high-helix lead screw,speedy multi-start lead screw,or steep lead screw features a high pitch that is used to transform a smaller radial movement into a large axial movement.

3.M ISO Metric Thread (60°)

The most common form of thread used for fastening and precision transmission.

4.A  ACME Thread (29°)

Inch threads can also be used for fastening connections,but not for high accuracy.

5.R Knuckle Thread

With the same arc thread as ball screw,the transmission is smoother.
