Double end stud bolts are also referred to as threaded rods. The manufacture of these fasteners by any Double End Bolt Manufacturer In India is with the construction of thread length at both ends. The thread lengths present on each side of the Double Ended Bolt Screw are constructed equal. Generally, the Double Ended Connecting Bolt has a plain shank that is equal, just like that of the nominal diameter. The main reason for using Double End Threaded Stud Screw Bolt in applications is that they exhibit high strength bolting.
While these fasteners are produced using various materials, the most common type is Double Ended Bolt Snap Stainless Steel. Yet, because there are several grades of stainless steel available in the market, the characteristic of this fastener will be based on the grade of alloy used for its manufacture. Economical stainless steel Double End Swivel Bolt Snap fasteners will be produced from grade 304. On the other hand, better quality is grade 316, which is also known as marine grade.
The forming processes used on Double End Threaded Bolt could be either cold forging or hot forging, both of which have their respective benefits. This type of fastener is mostly employed while attaching flanges or pipes together. The Double Ended Stud Bolt length of thread would vary depending upon the requirement of the application. The Double Ended Hex Bolt is manufactured with equal length threads on each end in order to support a nut. The use of Double Ended Lag Bolt is suited to flange bolting or even those applications where torching is required from both sides.
