Centor Free Thread Data/Check

This app provides all data required to machine and measure screw threads to your selected tolerance band. Effective Diameter (Pitch Diameter) tolerances and readings over selected wire or pin size are calculated for that tolerance.
Any wire/pin size can be input within calculated allowable range to give readings required for screw thread measurement using the 3 wire method.
Thread forms provided include ISO metric 'M' Form, the modified metric 'MJ' form, Unified 'UN' form, modified 'UNJ' form and British Standard Whitworth Form ('BSW', 'BSF' & 'BSP') plus others.

THIS FREE VERSION IS RESTRICTED TO 8mm to 20mm OR 3/8" to 5/8" DIAMETER THREADS, #1BA & G1" (BSPP)

Allowance can be made for PLATING or coating thickness with the use of a 'Slider' scale adjustment.
Wire/Pin Readings for Internal Threads are provided as 'GO' & 'NO GO' GAUGE sizes. This enables the manufacture of temporary soft gauges if necessary.
Final calculations can be held on screen or saved as .pdf file which can also be output to WIFI printer if available and correctly set up.

Full version to accept any Diameter/Pitch/TPI combination is available at £2.49 (Usually £4.99) - Search search ‘CENTORPE’
