The software QMSys Threads, Tools and Gauges is a professional thread engineering program for calculation of external and internal threads, tolerances and fits for linear sizes, thread and plain gauges, thread cutting and forming taps, designed for engineers, metrologists, quality control managers, and mechanics. The results are based on international and national standards, guidelines and regulations and comprise information about nominal and limit values of thread parameters for threaded products, cutting tools, working, setting as well as checking gauges.

A useful feature of our product is that the thread parameters can be chosen from the respective list or can be inserted directly; this facilitates and smoothens the work process, since it is not necessary to remember the designation of each thread type. Another useful feature is that after entering the thread parameters, all types of working, setting and checking gauges are being calculated, thus, the user does not have to bother with repeated entry of the same data for different gauges.

Other valuable features include:

- Compliance with the latest revisions of ISO, EN, DIN, ANSI, ASME, BS, JIS, IS, SAE, API and other corresponding national standards

- Calculation of almost all types of thread and plain gauges

- Possibility for implementing additional thread types on client request

- Nominal and limit sizes on all thread and gauge characteristics - diameters, pitch, lead, flank angles, length of gauge and tolerance steps, etc. 

- Corrections for all types of finishing

- Calculation of indicated values by measuring the pitch diameter with three wires or three balls with consideration of the influence of a measuring force and deformation

- Design and inspection of thread cutting tools and working and check gauges

- Product design – selection of threaded joints

- Information is provided in both inches and millimeters

- Adaptive templates for reports, specifications and other documents by means of a text processing software

- Optionally, an automatic generation of designs is offered for screw thread gauges

- Printing in RTF and TXT files

- Regular updates and upgrades

- User-friendly interface

- Professional customer support
