A sawtooth thread is a thread profile with asymmetrical flanks, one of which is nearly vertical and the other slanted. This geometry resembles a saw blade. Sawtooth threads are used in particular in applications where axial forces must be transmitted in a single direction.
Special Features
- Unidirectional force transmission: High axial forces are transmitted almost entirely in one direction
- Higher efficiency: The angled edge reduces friction losses
- Self-locking: When the angle of inclination is correct, the connection cannot slip backward
Typical Applications
- Pressen und Spannvorrichtungen
- Presses and clamping devicesSchraubstöcke
- Machine Tools
- Lifting columns and jack stands
Characteristics
- Side profile: asymmetrical, with one side nearly vertical and the other gently sloping
- Load capacity: high axial load capacity in the direction of the load
- Feed rate: higher when less torque is required
- Friction characteristics: efficient thanks to the angled flank
