Absolutely the
most complete, fastest and accurate thread software program on the market.
Telephone walk thru for new users, free technical support available with a phone call.
This is a complete thread engineering program, not a database.
One input provides gage and product dimensions
for every thread type with STETFS software. Most typing
is done by the program’s point too menu system. The only typing required is the
nominal major diameter and number of threads per inch. The user then points to
the rest of the thread data required in popup menu dialog boxes. The program
then types the selected data eliminating costly typing errors. Coating
allowances are provided for minimum and maximum coating thickness on product
and gages.
UNR and UNJ root radius with crest and root width provided as well as drill size hole. Applicable specifications are shown at top of each page. Best, Exact and Optional over wire measurements are given for single and multiple start threads. The wire diameter required is calculated for the measurement type selected. The user may use an optional wire diameter when the best or exact wire diameters are not available. All programs in the set have several options that you access through the Edit options menu, such as altering the pitch diameters, changing product thread class, or gage class without having to repeat the data entry cycle. The required dimensions and tolerances are provided for the internal and external product threads, including dimensions for working plug gages, setting plug gages, Hi-Lo setting plug gages, ring gages and minor diameter gages.
STETFS is a Windows operating
system software and will run with Windows 98, ME, XP, NT,
Screw thread dimensions
and tolerances are done to the latest available standards for all thread types
listed below.
