3TY-06E type bolts are reliable because they are professional

Type bolts
We produce type bolts with the most advanced technology, ultimate materials, and top technical personnel
The meaning of bolt performance grades is divided into three grades for steel structure connection bolts, among which and above Bolts are made of low-carbon alloy steel or medium-carbon steel and have been heat treated (quenched and tempered). They are generally called high-strength bolts, and the rest are called ordinary bolts. The bolt performance grade label consists of two parts of numbers, which represent the nominal tensile strength of the bolt material. value and yield-strength ratio. For example, the performance level of bolts
means:
, the nominal tensile strength of the bolt material is up to grade
, the yield-strength ratio of the bolt material is
, the bolt The nominal yield strength of the material reaches
performance level of high-strength bolts. After heat treatment, the material can reach
, the nominal tensile strength of the bolt material reaches level
, and the yield-strength ratio of the bolt material is < br/>, the nominal yield strength of the bolt material reaches
