Use of double head bolts
1.Used in large-scale equipment which need to install accessories, such as mirror, mechanical seal seat, reducer frame, etc. At this time, a double-headed bolt is used, one end is screwed into the main body, after the attachment is installed, the other end is equipped with nuts.Because the attachment is often disassembled, the thread will be worn or damaged, so it will be very convenient to replace the double-headed bolt. 2. When the thickness of the connecting body is very large and the bolt length is very long, the double-head bolt will be used. 3. Used to connect thick slabs and places can’t be used hexagonal bolts, such as concrete roof trusses, single-track beam suspensions of roof beams, etc.
