Product Description

High strength Screw connections have the advantages of simple construction, good stress performance, detachable replacement, fatigue resistance, and non loosening under dynamic loads, making them a promising connection method.B7 High-strength Screw,SA193-B7 High-strength Screw,ASTM High-strength Screw

High strength screws use a specially designed wrench to tighten the nut, causing a huge and controlled pre tension on the screw. Through the nut and backing plate, a pre pressure of the same size is also generated on the connected parts. Under the action of preload, a large frictional force will be generated along the surface of the connected component. Obviously, as long as the axial force is less than this frictional force, the component will not slip and the connection will not be damaged. This is the principle of high-strength screw connection.

High strength screw connections rely on the friction between the contact surfaces of the connecting components to prevent their mutual sliding. In order to have sufficient friction on the contact surfaces, it is necessary to increase the clamping force of the components and increase the friction coefficient of the contact surfaces of the components. The clamping force between components is achieved by applying pre tension to the screws, so the screws must be made of high-strength steel, which is why they are called high-strength screw connections.

In high-strength screw connections, the size of the friction coefficient has a significant impact on the bearing capacity. The experiment shows that the friction coefficient is mainly affected by the form of the contact surface and the material of the component. In order to increase the friction coefficient of the contact surface, construction often uses methods such as sandblasting and wire brushing to treat the contact surface of components within the connection range,American ASTM SA193-B7 high-strength screw
