High Strength Steel Black Structure Hex Bolts DIN6914

Steel Structral bolts are a kind of high strength bolts and also a standard part. Fastening performance is better, for steel structure, engineering, so that the role of fastening. General steel structure, the requirements of the steel bolts are 8.8 or more, there are 10.9, 12.9, all of the high-strength steel bolts, and sometimes the steel structure is not the need for electroplating bolts.

SteelStructral bolts are mainly used in steel structure, used to connect the steel structure of the connection point.Steel bolts are divided into torsional shear high strength bolts and large hexagonal high strength bolts, large hexagon high strength bolts are high strength grade of ordinary screws, and torsional shear high strength bolts are improved in large hexagon high strength bolts, in order to better construction.
