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.

Reduce Costs by Using Captive Screws
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.
Advantages of Using Captive Fasteners
Captive screws help control costs by minimizing damage to machinery from loose screws and by reducing the need for replacement fasteners. Captive screws also help make repairs easier by allowing easy access to components.
Captive Screw Configurations
Captive fasteners are available in a variety of configurations and designs.
Style | Locking Style | Drive Style | Materials |
Flush Captive Screws | Flare-In | Philips | Steel |
Spring-Loaded Captive Screws | Broaching / Spline | Slotted | Stainless Steel |
