Who needs QMSys Threads and Gauges?
The software QMSys Threads and Gauges is a powerful thread engineering program designed for engineers, metrologists, quality control managers, machinist to save time and prevent human errors in determining nominal and limit values of thread parameters. The program is especially useful in the manufacture and control of threaded products and tools by saving time and costs for supplying standards and computations. 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 check ing gauges.
QMSys Threads and Gauges provides thread data on pitch diameters, major diameters, gage data, part data, helix angles, product and gage tolerances, crest and root flats, wire sizes, constants, and just about anything on threads one needs to know. The software assists users in the following activities:
- thread measurement and control – determining the nominal and limit sizes of external and internal threads
- gauge inspection – determining the nominal and limit sizes of working, setting and check ing thread gauges
- product design – selection of threaded joints.

Advantages of the QMSys Threads and Gauges software
- Computation of thread gauges according to ISO and ANSI/ASME standards.
- Statistic computation of the corrections for surface coatings - in view of the larger diameter tolerances before coating it leads to the lowering of the production costs.
- Computation 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.
- Information is provided in both inches and millimeters.
- Customers can provide themselves or adapt the 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.
