Double End Threaded Stud GB 899, more accurately known as GB 899 stud, is a fastener with specific standards and characteristics. Double End Threaded Stud GB 899 has a structure with threads at both ends and a smooth rod in the middle. The lengths of the threads at both ends are not equal, so it is also called unequal length stud. This design allows one end to be screwed into a nut, and the other end can be screwed into a workpiece or through a hole in the workpiece, and then the nut is tightened and used with washers and spring washers to connect the workpieces together. Due to the structural characteristics of the stud, it is particularly suitable for occasions where the connected parts are thick or bolts are not suitable due to structural limitations. A reliable connection effect can be achieved through the close fit of the threads at both ends and the tightening of the nuts. Double End Threaded Stud GB 899 is widely used in many industries such as machinery, aerospace, automobile manufacturing, petroleum, forging, textiles, wind power generation, etc.
