The loose panel screw (spring screw) can be used to install PCB board, occupying only a small space. The riveting sleeve of the hand tightening screw has embossing teeth, which is pressed into the case or thin plate hole (Note: if the drilling hole diameter of the thin plate corresponds to the pressing tooth diameter of the spring screw, please refer to the following technical parameters) to form an exposed spring screw, and screw the other end (i.e. the hand screwed end) by hand. Because there is a spring fixed in it, the screw goes in and out relative to the other end of the sheet metal. The scheme solves the problem of removing screws frequently, and is very convenient and practical.
