QMSys Threads

QMSys Threads is a really handy thread engineering program made just for engineers, metrologists, quality control managers, and machinists. If you work with threads in any way, this tool is super useful!

Explore Predefined Threads

This software lets you dive into a bunch of predefined threads. You can even tweak their properties to fit your specific needs. So whether you're looking to adjust some measurements or check tolerances, it’s got your back.

International Standards Compliance

The results you get are based on international standards. This means you'll find all sorts of important info about values and tolerances for threaded products. Plus, it covers working gauges, plug and ring gauges, and checking gauges too.
