The benefits of combination screws may not be fully understood by people in the industry

I believe that many people don't know much about combination screws. In fact, combination screws are divided into iron combination screws and stainless steel combination screws according to the choice of materials. This is just the difference in material.

And there are also choices for the national standard number of combination screws, including GB9074.4, GB9074.8, GB9074.13, etc. These are just different national standard names for combination screws, such as GB9074.4 is a large pan head combination screw, GB9074.8 is a small pan head combination screw, and GB9074.13 is an external hexagon combination screw.

The function of the combination screw is also very simple, that is, to connect and fasten product objects. Because the elastic flat washer is rubbed on the screw, there is no need to use the elastic flat washer when using it. And when using it, the combination screw has another particularly important function, which is to prevent loosening.

The advantage of combination screws is that they save time for manual preparation of spring washers, and also improve the efficiency of screwing in some electronic and electrical manufacturers that use a lot of screws. Some manufacturers that use a lot of screws need to use spring washers on some products when screwing. They have to use spring washers one by one. This is very time-consuming, labor-intensive, and costly.
