What is a high strength screw?
Since high-strength screws are different from ordinary screws, their process flow will also be unique.

It is divided into three parts. The first step is the pretreatment process, which includes pre

electroplating accuracy and appearance inspection, manual degreasing, soaking degreasing,

pickling, electric activation and other processes. Then there is the electroless nickel plating process,

and finally the post-treatment process, including hydrogen drive heat treatment, finished product

inspection, etc.

The material of high-strength screw is made of high-strength steel, and its strength grade is twice as

large as that of ordinary screw, so its load must be much larger than that of ordinary screw. On the

other hand, the connection of high-strength screws transmits external force by applying preload and

friction. The ordinary screw is connected by the screw, and the shear force is transmitted by the

shear resistance of the screw rod and the pressure on the hole wall. The and pressure after

screwing is negligible, while the friction between the screw and the nut increases because of the

preload generated by the high-strength screw. From the material point of view, it itself is made of

high-strength steel; When in use, it needs to apply a greater preload than ordinary screws; In terms

of performance, the performance grade of high-strength screws should reach above grade 8.8. In

these differences, high-strength screws and ordinary screws are also different in use. High-strength

screws are generally used for permanent connection, so they are mostly used in buildings, while

ordinary screws can be reused, and some electrical equipment to be repaired can be seen very often.
