WebJul 28, 2024 · Finding the lead angle is the first step in analyzing a power screw system. Figure 6.4.3: The lead angle of a screw is the angle of the thread that the nut will be climbing up as the shaft rotates. Once we find the lead angle, we can draw a free body diagram of the "nut" in our unwrapped system. Here we include the pushing force which is ... WebAnything less than ¼” will be labeled from #0 to #12. #0 has an outside diameter of 0.06 inches, while #12 has an outside diameter of 0.216 inches. After #12, the gauge size is labeled according to the outside diameter. If the screw has an outside diameter of 0.25 inches, the gauge size will be ¼”, and so on.
