Steel connecting bolts performance grade points 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. More than grade 10, 8.8 and above screw material low carbon alloy steel or medium carbon steel and heat treatment (quenching, tempering) , Usually called high-strength screws, the rest are called ordinary screws. The screw performance rating label has two parts, namely the tensile strength and the yield ratio of the nominal screw material. Titanium screw manufacturers analyzed, for example, the performance level of 4.6 screws, which means:


1. The nominal tensile strength of the screw material is 400 mpa;


2. The yield strength ratio of the screw material is 0.6;


3. The nominal yield strength of the screw material is 400×0.6 = 240 mpa performance level
