双头螺柱、牙条又称为螺柱,由于其长螺纹的特性,适合于连接厚度大的场景,在船舶及海洋工程中，多用于连接厚板和不便使用六角螺栓连接的地方,如混凝土平台层、屋面梁悬挂等。在船舶工业中,多安装在需要安装附件且主体为大型的设备,由于附件是经常拆卸的,螺纹会磨损或损坏,使用螺柱更换会非常方便。同时化工行业多要符合A193/194标准,产品多需进行固溶处理。
Double-head studs and thread bars are also known as studs. Due to their long thread characteristics, they are suitable for connecting thick objects. In ships and marine engineering, they are mostly used to connect thick plates and places where it is inconvenient to use hexagon bolts for connection,such as concrete platform floors, roof beam suspension, etc. In the shipbuilding industry, most of them are installed in large equipment that need to be installed with accessories. Because the accessories are often removed, the threads will be worn or damaged, and it should be very convenient to replace them with studs. At the same time, the chemical industry should comply with the A193/194 standard, and the products should be subject to solution treatment.
