Tips

The performance grades of bolts for steel structure connection are divided into more than 10 grades, such as 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, and 12.9. The bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel. After heat treatment (quenching and tempering), they are generally called high-strength bolts, and the rest are generally called ordinary bolts. The bolt performance grade label consists of two numbers, which respectively indicate the nominal tensile strength value and the yield ratio of the bolt material.

Specification
Gi Spring Screw Grade 8 Bolt and Nut
The difference between bolts and screws lies in two aspects: one is the shape, the stud part of the bolt is strictly required to be cylindrical, used to install the nut, but the stud part of the screw is sometimes conical or even with a tip; the other is Using the function, the screw is screwed into the target material instead of the nut. In many occasions, the bolts also work individually, and are directly screwed into the pre-drilled threaded hole, without the need for a nut to cooperate with it. At this time, the bolt is classified as a screw in terms of function.
