What Is The Difference Between High Strength Bolts And Ordinary Bolts？

There are many varieties of bolts, which are decided according to different application needs and environments, the so-called high-strength bolts are a kind of bolts that can withstand greater weight, and there are many differences between such high-strength bolts and general products, which is why manufacturers produce so many different types of products that can be used in different ways, so do you know what the differences are between high-strength bolts and general bolts? Do you know the difference between high strength bolts and normal bolts?

First point: from the raw materials:high-strength bolts are made of high-strength materials. High-strength bolts screw, nut and washer are made of high-strength steel, commonly used 45 steel, 40 boron steel, 20 manganese titanium boron steel. General bolts are commonly made of Q235 steel.

The second point: from the strength level:high-strength bolts, the use of increasingly widespread. Commonly used 8.8 and 10.9 two strength grades, of which 10.9 grade mostly. General bolt strength grade to lower, generally 4.4, 4.8, 5.6grade. (8.8S and 10.9S are special for steel structure)
