Specialty Taps
These unique groups of tools all have a specific application where they are most suitable. As a company who specializes in custom taps we have chosen to continue to offer these both as standard and when needed special to meet the customer’s need. Each has a purpose related either to the thread form as in the case of Acme, National Special or Whitworth, or in the design making the application of the specific style the most efficient for the purpose of tool life performance.

Taps with NS or National Special threads are supplied from stock in our Roscoe Illinois warehouse. If not in stock we will make overnight and ship the next day.
ACME taps have a 29 degree thread angle and the thread height is one half of the pitch. This style thread is common in lead screws and other load bearing applications.
Nut taps are designed to thread nuts in small lot sizes or used because of the long entering chamfer. Longer than standard taps they can also be used to reach the thread section of a part.
The lead of a tap is the distance it will travel along it's axis in one revolution. A double lead will travel twice that distance in one revolution. The most common use is in adjusting mechanisms where a clockwise turn will make a linear distance movement twice the distance of a single lead.
British Standard Whitworth taps were the first to set standards for consistent dimensions. Regal provides 55 degree thread angle taps made on American ANSI standard blanks.
