The composition of the captive screw is divided into several components:
  1. Screw part (the other end of the thin plate of the chassis is fastened by it, the general material is carbon steel and stainless steel, and the head has a cross or a slot to facilitate tool tightening)
2. Hand-twisting sleeve (usually straighten the pattern, the material is usually aluminum, sometimes it needs to be blackened by aluminum oxidation)
3. Pressure riveting sleeve (rivet on the panel and rely on it)
4. Spring (to facilitate the extension and retraction of the screw and keep the whole part from falling out)
