Code for acceptance of high strength bolts

We should check whether there are high strength bolts in the packing box with high strength. The weight of each box shall not exceed 40 kg.

As for how to separate the packing case, it is entirely up to the manufacturer to choose. On the outside of the packing case, there should be the name of the manufacturer, the name of the product, the standard number, batch number, specification and quantity of the product. More strictly, it should be marked with obvious marks such as gross weight. During the inspection, we should check the quality inspection report and factory certificate provided by the manufacturer.

When leaving the factory, it needs to be tested according to the batch. The same performance grade and the same heat number and thread specification length are the same batch number. Mechanical processing, heat treatment process and surface treatment process are the same batch number.

It should be noted here that the maximum quantity of high-strength bolt connection pairs to ensure the supply of torque coefficient is 3000 sets.
