First of all, we have to check the packaging, check whether the box is strong and moisture-proof, etc. The box body should be a combination package of high-strength Threaded Rods And Eye Bolts. According to regulations, different high-strength bolts cannot be mixed and installed. The quality of each box also has certain requirements and cannot exceed forty kilograms.
As for how to divide the packaging box, it is entirely up to the manufacturer to choose. On the outside of the packing box, there should be the name of the manufacturer, the name of the product, the standard number, the batch number specification and quantity of the product, and the gross weight and other obvious signs should be more strict. When inspecting the goods, check the product quality inspection report and the certificate of conformity provided by the manufacturer on a batch basis.
When leaving the factory, it needs to be tested according to the batch. The same performance level and material, the heat number and the thread specification length are the same batch number. The bolts of mechanical processing, heat treatment process and surface treatment process are the same batch number. One thing to note here is that the maximum batch of high-strength Hexagon Flange Bolt that guarantee the torque coefficient is 3000 sets.
