Stub Acme Thread Gauges

STUB ACME Threads are similar to ACME threads except that the thread depth/ height is less than ACME. These are used for thin walled applications, where coarse pitch is needed like tubes used in Oil fields equipments, where standard ACME threads can not be used due to thin wall.
