![]() ![]() UTS threads do not usually use the pitch parameter instead a parameter known as threads per inch (TPI) is used, which is the reciprocal of the pitch. For UTS threads, which are single-start threads, it is equal to the lead, the axial distance that the screw advances during a 360° rotation. The pitch P is the distance between thread peaks. The outermost 1⁄ 8 and the innermost 1⁄ 4 of the height H of the V-shape are cut off from the profile. ![]() In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. UTS threads consist of a symmetric V-shaped thread. Only the commonly used values for D maj and P differ between the two standards.Įach thread in the series is characterized by its major diameter D maj and its pitch, P. Greenfield Ave., in downtown West Allis, where we still reside today.The basic profile of all UTS threads is the same as that of all ISO metric screw threads.
