A: Size：M4-M100，1/2“-4”
A: Material：Q235/C45/16Mn/65Mn/35CrMo/42CrMo, B7 etc
A: Surface：Plain, black oxide, galvanized, HDG, YZP, dacromet, etc
A: B7 studs are sheet metal fasteners that are very similar to a bolt. Unlike a bolt, however, the stud does not have a head. The B7 in the name of the stud is a grade of steel alloy. They host high tensile strength and are generally used in high pressure and high-temperature environments.
A: UNC Threaded Bars have a 60-degree thread flank angle, but like other Threaded Rods are essentially metal bars (made from mild steel or brass) that have a helical thread all the way along its length.
A: ASTM A193 Grade B7 fully threaded rods and studs provide high wear resistance, high temperature resistance, and high strength. Made of alloy steel that has been heat treated, they are typically used in high pressure applications, such as valves and pressure vessels in petroleum and chemical equipment.
