WebIt relies on the sliding of the screw shaft and nut threads with no ball bearings between them. The types of lead screws based on their thread geometry are square threads, acme threads, trapezoidal threads, and buttress threads. Lead screws may be manufactured by a thread rolling or a thread whirling process. WebLength, Nut End Thread - 2-1/2 x Diameter = Minimum thread length of full threads measured from the end of the stud. Length, Tap End Thread - One diameter + maximum point = minimum thread length, measured from the end of the stud to the end of thread run out (to the last scratch on cut threads, or to the last impression of threads made by other ...

Web8UN - 60 Degree Unified Threads. The 8-thread series (8-UN) is a uniform-pitch series for large diame- ters. Although originally intended for high-pressure-joint bolts and nuts, it is now widely used as a substitute for the Coarse-Thread Series for diameters larger than 1 inch. 1 1/16" - 1 11/16" 1 3/4" - 2 5/8" 2 3/4" - 3 3/4" 3 7/8" - 4".
