Screw thread and Gear measurement Screw thread measurement: Elements of measurementerrors in screw threads-measurement of effective It is the value obtained by subtracting the design tooth /5(3). POWER SCREWS (ACME THREAD) DESIGN. There are at least three types of power screw threads: the square thread, the Acme thread, and the buttress thread. Of these, the square and buttress threads are the most efficient. able to overcome the tendency for the load to "slide" down the plane, and the load will fall due to gravity. In most cases. Screw Thread terminology Pitch: The distance from a point on a screw thread to a corresponding point on the next thread measured parallel to the axis. Lead The distance a screw thread advances in one turn. For a single start threads, lead=pitch, For double start, lead=2xpitch, & so on.
