It is particularly useful wherever drill strings are used and in well drilling operations.

It is to be used in identifying drill stem connections on which the identification markings have worn off or are illegible. The end profiles on this gauge will help you determine the number of threads per inch in the pin or box. Use calipers to measure the diameter at base on the pin, transfer this measurement onto the gauge and quickly determine the type of joint. The numerals following the type of joint on joint tool identifier indicates the number of threads per inch. To identify the type of box, hold this gauge to the counterbore opening and read the corresponding graduation on the tool joint identifier. Be sure the corresponding threads per inch are also correct.
