We recommend

Metric screw threads
Determine nominal sizes of metric screw thread. Calculate its limits of sizes as well as tolerances and deviations.
Trapezoidal threads
Determine nominal sizes of metric trapezoidal screw thread. Calculate its limits of sizes as well as tolerances and deviations.
Gauges for checking metric screw threads
Design gauges for checking metric threads. Determine parameters of working, check, wear and setting gauges. Calculate nominal and limit sizes of all gauges as well as their tolerances, deviations and permissible wears.

Our applications

Use our programs to quickly and correctly design the element you are interested in.
