American Standard Bt.1-1949 was the first American standard to cover those
Unified Thread Series agreed upon by the United Kingdom, Canada, and the
United States to obtain screw thread interchangeability among these three
nations.


These Unified Threads are now the basic American standard for fastening
types of screw threads.


UNF -  fine thread series, this series is suitable for for production of
bolts, screws,
           and nuts and for other applications where Course series thread is
not applicable.


Thread Classes  -  Thread classes are distinguished from each other by the
amounts of tolerance and allowance.
                             2A and 2B -  are most commonly used for general
applications.

Hi all,

I hate to display my ignorance but I need to know what  #10-32 UNF-2B thru
means. I understand it is a treading requirement with a 10-32 tap but I dont
know what "UNF-2b thru"means.

Thanks

Ed Cosper
