12.9 - level six - angle screw is one of the most commonly used series of high - strength bolts.
In the 12.9 stage of the supply of the company with the company, the six angle screws are generally used for the high requirements of mechanical properties, such as injection molding machine, hydraulic equipment, mold assembly and so on. The national standard of the six angle cylinder head screws is GB70-1985, DIN912.,, M6-1.0*22, M6-1.0*25, M6-1.0*30, M6-1.0*35, M6-1.0*40, M6-1.0*20, and the size of the national standard
12.9 angle screws after heat treatment of the surface hardness can reach 39-44 degrees.
12.9 inner six angle screw production standard reference to the national standard GB/T70.1, German standard DIN912, American Standard, British standard production.
12.9 level six angle screw part of the specification of the full thread, half thread, fine teeth.
American 12.9 inner hexagon screw supply range from #4--1-1/2, imperial 12.9 inner hexagon screw supply range from 1/4--1-1/2 commonly used specifications are spot sales.
Performance grade 10.9 high strength bolt, the material after heat treatment, can achieve:
1, bolt material nominal tensile strength of 1000MPa grade;
2, the bolt material of the yield strength ratio of 0.9; bolt material nominal yield strength of 1000 x 0.9=900MPa.
