What is a Captive Screw?

Captive screws are specially designed to lock into pre-drilled holes so that the screw can be fastened and unfastened without the screw being detached. One of the primary benefits of captive screws is that they provide secure fastening while reducing costs associated with lost screws or damage from foreign object debris (FOD). Captive screws are available in a variety of styles and materials to suite diverse application needs. Captive screws are frequently used in electronic enclosures, exhibits/signs, medical devices, and network cabinets.

What is a Captive Screw?

Captive screws are designed to lock into a hole while allowing the fastened components to be detached without the complete removal of the screw. Thus a captive screw can be locked in place on a parent component without being fastened to a child component. Captive fasteners are typically locked in place using thread locking, press-fitting, or broaching.
