We are offering a Trapezoidal Thread Gauge, which is used for translation motion in machine tools like lead screws, where rapid movement is required or in screw jacks, where load to be shared is more. This gauge comes in 2 shapes: square thread forms and trapezoidal thread forms. The majority of lead screw designs for power transmission employ trapezoidal threads gauge because they are more straightforward to manufacture and have better load capabilities than square-threaded screws.
