Centor Thread Check Trial

Calculates data for machining screw threads and check using three wire method.

FULLY FUNCTIONING FREE TRIAL VERSION WITH LIMITED SIZE RANGE FOR DEMONSTRATION ONLY.

This trial version has all features of the premium version but is restricted from 8mm to 12mm diameter input for metric threads or 3/8" to 1/2" diameters for imperial threads.

OPTION OF INCH OUTPUT AS ALTERNATIVE TO METRIC DEFAULT.

Now with 'ThreadFinder' option which lists parallel threads of all available types which have similar diameter to measured diameter of sample thread. These are listed in order of Pitch/TPI.

Select from various threads including ISO metric 'M', the modified metric 'MJ', Unified 'UN', modified Unified 'UNJ' and British Standard Whitworth form ('BSW', 'BSF', 'BSPP' & 'BSPT') & NPT plus others.

Current version now has BSPP/BSPT variations (G, R, Rc & Rp) and Pg, Metric Fine and BS CONDUIT threads are available. NPS, Dryseal Pipe Threads plus ACME options are currently under development. Note: NPS selection screen and listings are present but calculations are still being worked on.

This thread calculator app provides all data required to machine and measure screw threads to standard tolerance band selected from a drop-down menu.

Standard sizes are selected at a touch from scrolling list. In premium version Non-Standard threads can be input from keyboard in any Diameter & Pitch/TPI combination. (restricted in this trial version).

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.

Results can be output to WIFI printer if correctly set up with your printer manufacturers print service software on your device.

Default results are in MILLIMETRES with INCH output as optional selection.

The app contains no adverts but does have links to most major THREADING INSERT SUPPLIERS in order to help with sourcing required tools.

A PREMIUM VERSION is available with scrolling selection from complete listing of all STANDARD SIZES or to accept keyed input of any NON-STANDARD COMBINATION of Diameter & Pitch/TPI - Use upgrade links within this trial version or download at:-
