What is A Captive Screw?
A captive screw, also known as a captive fastener, is an engineered fastener designed for a permanent hold within a target assembly or housing, including during servicing. It provides a secure joining, and avoids fastener loss or damage that might be caused by a loose part.
Captive screws are widely used in applications across various industries, including:
1. Electronics: For securing panels and covers on computers, servers, networking equipment, and other electronics where frequent access may be required for upgrades or repairs.
2. Aerospace: In aircraft cabins and panels, where vibration might loosen fasteners, and loose parts can pose safety risks.
3. Telecommunications: In equipment racks and enclosures that require regular maintenance or inspection.
4. Medical Devices: For securing components in devices that need regular cleaning, sterilization, or adjustment, while ensuring parts are not lost or misplaced.
