Characteristics of high strength bolts High strength bolts are made of high strength steel, or bolts that need to be applied with large preload, which can be called high strength bolts. High strength bolts are mostly used to connect bridges, rails, high pressure and ultra-high pressure equipment. The fracture of this kind of bolt is [...]
Today, We will introduce the classification of high strength bolts. According to the stress state, high strength bolts can be divided into friction type and pressure bearing type. In fact, there are differences in design and calculation methods. The ultimate bearing capacity of friction type high-strength bolts is the sliding between plates; The bearing capacity [...]

In order to distinguish high strength bolts, the following three methods are mainly used: With naked eyes, high strength bolts can be divided into high-strength external hexagon bolts and high-strength inner hexagon bolts. These high strength bolts are generally marked with strength grade and hardness grade. Generally, the screw head is marked with bolt grade. [...]

High Strength Bolts Bolts made of high-strength steel or requiring large preloading force can be called high-strength bolt. High-strength bolts are mostly used to connect bridges, rails, high-pressure and ultra-high-pressure equipment. The fracture of this kind of bolt is mostly brittle fracture. In order to ensure the sealing of the container, the high-strength bolt used [...]
The degree of tightening of ordinary bolts is not clearly defined, and the force applied during locking is generally as long as the connection is tight. However, since the tension is not applied when the lock is applied, the nut is prone to loosening. To prevent loosening, the inner nut can be pressed by the [...]
The riveting bolts were still widely used until the 1950s, but the construction process of the riveting bolts was not only dangerous but also difficult for professional technicians. It also produced noise resistance during construction, and the construction quality was difficult to control due to the strength and clamping efficiency of the riveting bolts. In [...]
