Standard sizes are selected at a touch from scrolling list. Non-Standard threads can be input from keyboard in any Diameter & Pitch/TPI combination.
LIMITS OF EFFECTIVE DIAMETER (PITCH DIAMETER) are displayed in addition to MEASUREMENT OVER SELECTED WIRE/PIN size. Both are calculated for the selected tolerance band.
All standard tolerance bands are available from drop-down menu and allowance can be made for PLATING or coating thickness with the use of a 'Slider' scale adjustment.
Software calculates the range of acceptable wire/pin sizes and any available pin which is within that calculated allowable range can then be input. The readings calculated give measurements required for screw cutting and screw thread inspection using the 3 WIRE METHOD or Effective/Pitch Diameter tolerances are given for use with direct measurement methods.
Readings over pins 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 or saved as a .pdf file.
