V Threads at Work

Metric ISO threaded screws are V-shaped at the outer edges, and are self-locking so do they not need a screw lock.The flank angle of a V thread is 60° and it is commonly used for all places where fine adjustments with leads as fine as 0.0125inch (0.3175mm) are critical such as microscope stages.

Sharp threads are also used as fastening screws for frictional connections such as screw connections with anti-fatigue shafts or tension anchors. Sharp V-threads are not well suited for linear motion applications or power transmission.
