We all know that in the combination screw, if it is a three-combination screw, it is generally a pan head screw or a hexagonal screw with a spring pad in a three-piece assembly with a flat pad combination. But in the flat pad, what are the specific requirements here! Next, Shenzhen Chuanggu Screw Manager Zhu will briefly introduce the specific requirements required to wear the flat pad in the combination screw.
In fact, in simple terms, there is no specific requirement for the flat pad in the combination screw. Just need a flat pad in the combination screw that needs to be worn on the front side. This kind of positive flat pad is a good look. However, if the requirements are not very high, then the flat pads in the combination screws are not required to be split. Anything positive or negative can be. But it is best if you can wear the front. Prevent customers from having different requirements for flat mats.
