Tap Shank and Drive Square dimensions
Sorted by Shank diameter
|
Note: This is a compilation of information from numerous on-line sources (manufactures, retailers, etc.). I do not have access to the actual Industry Standards that these sources are referenceing so I can not confirm the validity of any of this information. However, except where noted, all information on this page agrees with at least 2 independent web sources (but its possible that many of my sources are getting false info from a another source). I found many cases where two or more sources had blatently different values and in most of these situations I just left the conflicting information out of the table until I can resolve the differences. In a few cases I put the info in the table and added a note defining the sources and differences.
