High-Strength Grade 8.8, 10.9, 12.9 Hexagon Bolts

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.

High-Strength Grade 8.8, 10.9, 12.9 Hexagon Bolts

High-Strength Grade 8.8, 10.9, 12.9 Hexagon Bolts

Steel Structral 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.Heavy Hex Head Structural Bolt, 10.9 DIN 6914 1989/ISO 7412 High Strength – Property Class 10.9 – Coarse Thread Pitch – Partly Threaded – Heat Treated Steel – Hot Dip Galvanized For structural bolting with oversized across-flat pattern Bolts manufactured according to DIN 6914-10 standard, when matched with the oversized nut # 6915-10 and flat washer # 6916-(C45) provide an assembly with a level of assurance against failure by thread stripping if overtightened. Tensile Strength: Rm/ N/mm? 1040 minimum, Mpa 1040 minimum (150,800 psi) Please call to inquire about longer lengths and larger diameters.
