Product Description Widely used for the purpose of measuring the pitch or lead of a screw thread in several industries, this Unified Thread Gauges is quite asked for. For example, the major diameter of a 0000 screw thread is 0.060 in − (3 × 0.013 in) = 0.060 in − 0.039 in = 0.021 in. 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. Even though #14 and #16 screws are still available, they are not as common as sizes #0 through #12.

M Series Metric thread gages are manufactured per ASME B1.16M. 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. Choose from our selection of thread gauges, including size identifying, size checking, and more. 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. The thread pitch for an American National Standard Unified 60 ° thread is: E = M + 0.86603P – 3W Notice that if we know the pitch (P) and the wire diameter (W), then for … Price $59.85.

ASME UN screw thread calculator to calculate imperial unified screw thread basic major, minor, pitch diameters and thread tolerance for the external (bolt) and internal (nut) inch threads according to ASME B1.1 standard. The basic purpose and use of each gauge are also described. We are the Special Thread Gauge suppliers and manufacturers in India. Thread class refers to the acceptable range of pitch diameter for any given thread. To calculate the major diameter of "aught" size screws count the number of extra zeroes and multiply this number by 0.013 in and subtract from 0.060 in. Preferred sizes are 0.3, 0.4, 0.5, 0.6, 0.8, 1.0 and 1.2 mm, with additional defined sizes halfway between. Standardization efforts in the late 19th and the early part of the 20th century reduced the range of sizes considerably. Unified threads use nominal gauge sizes for the thread diameter and threads-per-inch (TPI) for the thread pitch.
