About Stud Bolts
Stud bolts are critical high-pressure fasteners engineered for environments where standard bolts cannot provide sufficient clamping force. As leading stud bolt manufacturers in India, Jade Alloys supplies precision-machined studs for pipelines, offshore drilling, refineries, petrochemical plants, and power projects. They are the primary choice for ensuring leak-proof sealing in flange connections.
While the all-thread stud bolt is the most common, we also manufacture tap-end and double-end varieties. In a tap-end configuration, the shorter end features a tight UNC 3A fit designed to be screwed directly into a tapped hole in a machined component. For flanged connections, specifications like size, length, and diameter are governed by the flange pressure class On ASME B16.5 standards.
We manufacture a comprehensive range of stud bolts configurations to meet diverse engineering requirements:
