A193 B8 Stainless steel 304 double ends thread stud bolt
Stud bolt used in high pressure bolting situations for pipeline, drilling, petroleum / petrochemical refining and general industry for sealing and flange connections all thread, tap end and double end stud bolts are the lion’s share of the industry. The all thread stud bolt is a threaded rod with 2 heavy hex nuts, while the tap end and double end are nut continuously thread, but have a body in the middle with one nut. In a tap end the short end of the stud bolt is designed with a UNC 3A fit to go into a tapped hole on the body of a larger machined or forged equipment.
