Solar Mounting Roof SUS304 SUS316 Metric Double End Thread Hanger Bolts

Solar Mounting Roof SUS304 SUS316 Metric Double End Thread Hanger Bolts

1.Product Description

Double head bolts generally need to pass surface treatment, bolt surface treatment of a lot of types, commonly used electroplating, blackening, oxidation, phosphating, non-electrolytic zinc coating treatment.However, electroplating fasteners occupy a large proportion in the actual use of fasteners.
Use in the main body for large equipment, need to install accessories, such as mirror, mechanical seal seat
Deceleration frame, etc.In this case, double-head bolt is used, one end is screwed into the main body, and nut is put on the other end after the attachment is installed. As the attachment is often removed, the thread will wear or damage, so it is very convenient to replace the double-head bolt.2, used for connecting body thickness is very large, bolt length is very long, will use double head bolt.3, used for connecting thick plate and inconvenient to use hexagon bolt connection, such as concrete roof, roof beam hanging monorail beam hanging parts.
In actual work, external load has vibration, change, material high temperature creep and so on can cause the friction to reduce, the positive pressure in the thread pair disappears in a moment, the friction is zero, thus making the thread connection loose, such as repeated action, thread connection will relax and failure.Therefore, must carry on the prevention loose, otherwise can affect the normal work, causes the accident.
