Bolt Performance Editor

Such as:

1. Bolts with performance grade 4.8 are defined as:

(1) The nominal tensile strength of the bolt material reaches 400Mpa level;

(2) The tensile strength ratio of the bolt material is 0.8;

(3) The nominal yield strength of the bolt material is 400X0.8= 320Mpa level

2. Bolts with performance class 8.8 are defined as:

(1) The nominal tensile strength of the bolt material reaches 800Mpa level;

(2) The tensile strength ratio of the bolt material is 0.8;

(3) The nominal yield strength of the bolt material is 800x0.8 = 640Mpa level

3. Bolts with performance class 10.9 are defined as:

(1) The nominal tensile strength of the bolt material is up to 1000Mpa;

(2) The tensile strength ratio of the bolt material is 0.9;

(3) The nominal yield strength of the bolt material is up to 1000X0.9= 900Mpa grade

The meaning of bolt performance grade is the international standard, the bolt of the same performance grade, no matter the difference of material and origin, its performance is the same, the design only chooses the performance grade.The strength grade of the bolt is 10.9, which means the shear stress grade of the bolt is 10.9GPa.
