Thread Stud. The fixed link function is used to connect the machinery. The double bolts are threaded at both ends, and the middle screw is thick and thin. Generally used in mining machinery, bridge, automobile, motorcycle, boiler steel structure, hanging tower, long-span steel structure and large buildings.

1, It is mostly used in the main body of large equipment, need to install accessories, such as mirror, mechanical seal seat, reducer frame, etc. At this time, the use of double-headed bolts, one end of the screw into the main body, the installation of the attachment after the other end with a nut, because the attachment is often removed, the thread will be worn or damaged, the use of double-headed bolts replacement will be very convenient. 2. When the thickness of the connecting body is very large and the bolt length is very long, double-headed bolts will be used. 3. It is used to connect thick plates and places that are inconvenient to use hex bolts, such as concrete roof truss, roof beam hanging monorail beam hanging parts, etc.
