QMSys Threads (formerly QMSys Threads and Gauges)

QMSys Threads is a powerful thread engineering program especially designed for engineers, metrologists, quality control managers, and machinist.

This utility offers you the possibility to explore various predefined threads then modify their proprieties according to your needs.

The results are based on international standards and comprise information about values and tolerances of threaded products, working gauges, plug and ring gauges as well as checking gauges.

Types of threads:  · Metric Threads (M, MJ, with large clearance, galvanized) · Unified Threads (UNC, UNF, UNEF, UN, UNR, UNJC, UNJF, UNJEF, UNJ, NC-5) · Whitworth Threads (BSW, BSF, Whit.S., Whit.) · ISO Parallel and Taper Pipe Threads (G, R, Rp, Rc) · ANSI Pipe Threads (NPT, NPSC, NPTR, NPSM, NPSL, NPTF, NPSF, NPSI, PTF-SAE Short, F-PTF, ANPT, NPSH, NH) · NFPA Fire-hose coupling threads (NH) · API casing, tubing, line pipe threads (LP, CSG, LCSG, TBG, UP LTBG, IJ TBG, BCSG, XCSG, LTC) · Trapezoidal Threads (Tr, ACME, STUB ACME) - Miniature Threads (M, UNM) - Metric, ANSI and BS Buttress Threads 33°, 45°, 52° · Knuckle Threads, general purpose, for the mining, Lifting Hooks (Rd) · Steel conduit threads (Pg) · STI Threads · Metric, Inch, Whitworth, ISO and ANSI Pipe Threads · B.A. Threads, B.S.C. Cycle · Threads · Gauges for non-standard and special threads.
