ThreadTech gives the answer to pitch diameters, minor diameters, gage data, part data, tap data, helix angles, tolerances, crest and root flats, wire sizes, constants and just about anything on screw threads one would like to know.

The program prompts the user with questions which must be answered correctly before continuing to the next question. If the user inputs a dimension that is geometrically impossible or impractical, the program will prompt you until usable data is input. All formulae and rounding techniques are consistent with the latest ANSI, ASME and government specifications. When calculated values don't agree with table values, the program displays the table values. Easy to use

No computer skills are necessary to operate the program. The program provides step by step on screen explanations. All data can be easily saved and printed.

The program runs on Windows NT, 2000, XP, VISTA and 7. ThreadTech was designed for engineers, planners, quality assurance and machinist to save time and to help eliminate human error. The comprehensive screw thread program takes confusion out of thread manufacturing and inspection. It takes the place of time consuming computations and searches for specifications.
