A stud bolt is a rod threaded along some or all of its length and used without a head. It fastens parts together with nuts, or by screwing one end into a tapped hole. Aniket Engineering manufactures custom stud bolts to your drawing at our manufacturing site in Mumbai.
The three forms of stud bolt
Stud bolts come in three main forms, and the grade is chosen according to the application:
- Fully threaded stud bolts have a thread along the whole length and are tightened with nuts.
- Tap-end stud bolts are threaded at both ends, with a shorter thread on the end that screws into a tapped hole and a longer thread on the nut end.
- Double-end stud bolts have equal thread lengths at both ends with a plain section between them, so a nut can be fitted on each side.
Names for these forms vary between industries, so if you send a drawing or describe the joint, we will confirm exactly what is needed.
Materials
We turn stud bolts from stainless steels, mild steels, high carbon and alloy steels, brass, copper and aluminium alloys. The right choice depends on the load, the temperature and whether the joint is exposed to moisture or chemicals.
Made to your drawing
Diameter, length, thread type, thread length at each end and finish are all set by your drawing or specification. We supply finishes such as nickel plating, zinc plating and black oxide. Our CNC turned components range already includes threaded studs, and batch sizes run from fewer than 10 pieces to more than 10,00,000.
Typical uses
Stud bolts are used in bolted joints in machinery and equipment, where a joint is opened and closed repeatedly, and in assemblies where components are clamped between two nuts. Our customers include automotive, equipment manufacturing, civil, plastic moulding and fabrication companies. See the industries we serve.
Complete your joint
We also make custom bolts, nuts and washers to go with your studs, and our quality control process includes roundness and surface texture checking to within 0.001 mm.
