STUD METAL END BOLT.
Stud Metal End Bolts are threaded rods with equal thread length at both ends. Tap end studs are also sometimes referred as double end stud bolts. Stud Metal End Bolt have plain shank equal to that of the normal diameter.
Double Metal End Bolt:
Double metal End stud bolts are used for high strength bolting. Further one type of double end stud bolts have reduced shank diameter as designed for special bolting. Din 2510 is specification for double end stud bolts with reduced shank. Metal End Stud bolts dimensions are defined in both metric and imperial sized with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread profile. These are produced across all material categories and astm specifications.
It is used in high-temperature or high-pressure environments or other special-purpose applications. Stud bolts are externally a threaded fasteners without a head, use with 2 nuts on either side. Substituting a usual bolt and nut assembly. They are prominently used in flange connections.It provides the ability to obtain much more accurate torque values as a result because the studs don’t twist during tightening as do bolts. The studs bolt remain stationary because during nut tightening, the studs stretch in one axis alone, so providing much more even and like accurate clamping forces
Stud Bolt General.
Stud Bolt can also be called threaded rod is a relatively long rod that is threaded on both ends; which may extend along the complete length of the rod. They are designed to be used in tension. Threaded rod in bar stock form is often called all-thread.
Stud bolts are available in national coarse (UNC) thread pitches, like generally used in traditional applications, which can be there are 8 threads per inch (“thread per inch”) for rod diameters above 1 inch. B7 is the most common specification grade.
Stud bolts b7 ASTM a193 for a flange connection will be given by the number of bolt holes in a flange, diameter and length of bolts. Because it is dependent of flange type and Pressure Class of flange.
It can be Used in high pressure bolting situations for pipeline, drilling, petroleum or petrochemical refining and general industry for sealing and flange connections all thread, tap end and double end stud bolts, so in the share of the industries.
