Double End Stud, Used to connect the fixed link function of machinery, double-headed bolts have threads at both ends, the middle of the screw, there are thick and thin. Generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, suspension towers, long-span steel structures and large buildings.
Main uses
1. Appendices, such as mirrors and mechanical seals, need to be installed for large-scale equipment in the main body.Reducer frame, etc. At this time, a double-headed bolt is used, one end is screwed into the main body, and the other end is equipped with nuts after the attachment is installed.
