Double End Threaded Studs, B7 Hex Bolts


Description:

ITA Fasteners is a leading A193 b7 stud supplier and manufacturer. Studs from ITA Fasteners are steel bolts which are threaded on both ends. After the stud is screwed and secured in the middle, two different objects can be secured on either side of the bolts. Made with stainless steel for increased durability, they are used for flange bolting using nuts on either side. These bolts are typically stronger than standard bolts as they are cast and forged with a single piece of metal.

The bolts find their application in industries like manufacturing, plumbing, construction, petrochemical and automobile manufacturing. But they can also be used for custom applications based on individual requirements. These bolts are galvanised and can be used in high temperature applications as well. Since these bolts offer the user with the option of attaching two objects to its ends, it can also be economical in large scale projects. Get in touch with us to place custom orders of any size.
