ASTM A320 L43 fully threaded PTFE coated stud bolt for flanges
In a flanged connection the size, length, diameter and number of bolt holes is dependent of flange type and pressure class of flange.
Stud Bolt grades and sizes are defined by industry standards in ASTM A193 and ASME B16.5 standards. Bolts are usually defined as a threaded fastener intended to be mated with a nut, while a screw can engage either preformed or self-made internal threads,A stud is an externally threaded headless fastener. One end usually mates with a tapped component and the other with a standard nut.
