Every thread has its own specifications..........it depends on which thread you need......for example....if you need VAM top or BTC....you can not get an integral joint (threads cut into the joint).....it has to be a coupling made up on pin..............but if you need hydril ph6 or hydril 513......you will get integral joint.
