Name: Captive Screw, Panel Screw, Spring Hand-Tight Screw

Material: Combination of carbon steel screw, carbon steel press rivet sleeve, and aluminum hand-twist sleeve; Combination of stainless steel screw, stainless steel press rivet sleeve, and aluminum hand-twist sleeve. The captive panel screws produced by Yaoda Hardware*** are entirely manufactured and assembled in-house, with the exception of the externally sourced springs, ensuring strict quality control.
The captive panel screw (captive screw) consists of several components:
1. Screw part (used to fasten the other end of the chassis thin plate; typically made of carbon steel or stainless steel, with cross or slotted head for tool tightening)
2. Hand-twist sleeve (usually knurled, typically made of aluminum, and sometimes anodized black as needed)
3. Press rivet sleeve (used for riveting onto the panel)
4. Spring (facilitates the extension and retraction of the screw and prevents the entire component from detaching)
After each component is produced, they are assembled into one unit. The hand-twist part is pressed to fit together with the press rivet part via the spring, forming a complete captive spring panel screw.
