Specifications and uses of hexagon flange bolts Flange bolts are integral bolts composed of hexagon head and flange plate (the gasket under the hexagon is fixed by the hexagon) and the screw (cylinder with external thread). It needs to be matched with a nut for tightening. Parts that securely connect two through-holes. Hexagon flange bolts are particularly common industrial equipment and appliances used in the industry. Today we want to talk about the basic specifications and uses of hexagonal...
Why are nuts all hexagonal? From the perspective of rotation, a regular quadrilateral is the best in theory, but the rotation angle of each operation must be slightly larger than 90 degrees, and the actual operation space may be limited and cannot rotate 90 degrees, so choose a smaller rotation angle; From the point of view of the use effect, the regular octagon can also be used in theory, but the edges and corners of the nut and the wrench do not cooperate well, and it is easy to slip off when...
Reasons of square nut cracking Nut cracking is not a small problem. The cracking failure of the nut is caused by many factors. When the square nut cracks, there will be small cracks on its four sides. Do you know what is the reason for the cracking of the square nut? During installation, the installation force distance is too large, the fatigue strength of the operating environment is too high, and the lack of timely tempering after quenching may cause the square nut to crack, or it may be due...
What is the difference between the often mentioned large hexagonal high-strength bolts ？ High-strength bolts are mainly used in steel structure engineering to connect the connection points of steel structure steel plates. According to the construction process, high-strength bolts are divided into two types: large hexagonal head high-strength bolts and torsional shear type high-strength bolts. Their connection performance and their own mechanical properties are the same, and the axial force of...
