Stud Bolts – Full Threaded Precision for High-Pressure Joints
Product Description
Full Threaded Stud Bolts are headless, straight shank fasteners threaded throughout their length. These are primarily used in high-tension and flange connections where nuts are fastened on both sides to secure two components tightly together.
At SM Fasteners, our full threaded studs are manufactured with tight dimensional tolerances and surface finishes to meet global quality standards. Available in a variety of diameters, lengths, and materials, they are ideal for high-pressure and high-temperature environments like refineries, power plants, and structural joints.
Applications
Stud bolts are the backbone of:
Flange Connections in Oil & Gas Pipelines
Pressure Vessels and Boilers
Refinery and Petrochemical Joints
Steel Structure Tensioning
Valve & Pump Assemblies
Automotive Engine Assembly
Subsea and Offshore Projects
