This app provides all data required to machine and measure screw threads to your selected tolerance band. Limits of Effective Diameter (Pitch Diameter) and readings over selected wire or pin size are calculated for that tolerance.
Select from various thread forms including ISO metric 'M', the modified metric 'MJ', Unified 'UN', modified Unified 'UNJ' and British Standard Whitworth ('BSW', 'BSF' & 'BSP') plus others.
All standard tolerance bands are available from dropdown selection and allowance can be made for PLATING or coating thickness with the use of a 'Slider' scale adjustment.
Any wire/pin size can be input within calculated allowable range to give readings required for screw thread measurement using the 3 WIRE METHOD.
Wire/Pin Readings for Internal Threads are provided as 'GO' & 'NO GO' GAUGE sizes which enables the manufacture of temporary soft gauges if necessary.
Final calculations can be held on screen, saved as a .pdf file or can be output to WIFI printer if available and correctly set up with printer manufacturers print service software on your device.
Default results are in MILLIMETRES with INCH output as optional selection.
