Key Features
Captive screws are designed to remain securely fastened to a panel or component,
even when fully unscrewed from a mating part.
This feature prevents loss of screws during maintenance or assembly.
The screws are typically used in situations
where safety, ease of use, and efficiency are crucial, such as in
electronics or mechanical enclosures.
