This system is analogous to the fits used with assembled parts. The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. 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. t. ASME B1.3M ASME B1.3M Œ . is half the included angle of the thread, in this case 30 degrees:[1]. Grainger's got your back. Price $59.85. These standards provide essential specifications and dimensions for the gauges used on Unified inch screw threads (UN, UNR, UNJ thread form) on externally and internally threaded products. We are the Special Thread Gauge suppliers and manufacturers in India. The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch. Thread gages are used to ensure the assembly of mating parts. Manufacturing Range : Thread Plug & Ring Gauges from No.4 (0.112”) to 10” In the Unified National Series the ½ inch size has 13 threads per inch, but the American Standard was 12 threads per inch.
