Shenzhen Yaoda hardware produces all kinds of screws used in panel: loose screw, also known as spring screw. The loose screw can be riveted on the iron plate and can be freely screwed in and out of the screw, also known as the screw without pulling out. The outer circle of the hand screw sleeve is generally pressed with ruled teeth to facilitate manual or manual tightening. At the same time, it is also called hand tightening screw or hand tightening screw.

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.
