GB/T 32076.4-2015 Preloaded high-strength bolt structure connection pairs-Part 4 large hexagon bolts
Product Overview:
Preload high-strength bolt structure connection pair is the use of high-strength steel and special connection mode, the components are connected together to form a whole device. In the process of connection, a certain load is applied in advance to make the connection pair have better performance in the process of stress. Each connection pair comprises a bolt, a nut and two washers. With high strength, high reliability. It is easy to install, easy to disassemble and assemble, and easy to construct.
Grade:
8.8, 10.9
