Stud Bolt

Stud Bolt or Studs,sometimes called Full thread rods are externally threaded fasteners that typically look like and operate as threaded bars. They’re different from screws and bolts in the fact that they don’t usually have a head that requires tightening — just continuous threading that can be paired with nuts

Stud bolts are the bolting material or fastener used to tighten the flange joint connection according to ASME B16.5 Code
