Captive screws are specialized fasteners designed to remain secured within a component or housing, featuring a non-threaded section known as the reduced shank beneath the head. This design ensures that the captive screw cannot be fully extracted from the hole or lost during disassembly. At Yuhuang Fasteners, we maintain a variety of sizes and materials for captive screws and offer custom fasteners tailored to your specifications, including size, material, and surface finish.
Captive screws come in various types, each suited to specific applications and designs. Here are some common types of captive screws:
Button Head Captive Screws
These have a small, domed head that sits flush with the surface, providing a neat and low-profile appearance.
Pan Head Captive Screws
Featuring a flat, round head, these captive screws offer a balance between a low profile and ease of use.
Thumb Screw Captive Screws
Featuring a knurled head for easy manual adjustment, these captive screws are convenient for applications requiring frequent assembly and disassembly.
Socket Captive Screws
These have a hexagonal or star-shaped indentation in the head, compatible with specific bit types for secure and precise installation.
Cup Head Captive Screws
With a small, concave head, these screws provide a smooth, finished look while remaining captive.
These types of captive screws can be further customized in terms of material, thread type, and surface treatment to meet the specific needs of various applications.
Captive screws are utilized in a variety of applications where secure, tamper-resistant fastening is required, and the fastener must remain attached to the component. Here are some common applications:
1. Electronics Enclosures: Securing covers and panels to prevent unauthorized access or to protect internal components.
2. Appliance Fastening: Holding parts together in household appliances where regular access for maintenance might be needed.
3. Automotive Interiors: Attaching trim, panels, and electronics within vehicles that require secure yet removable assembly for service.
4. Furniture Assembly: Joining parts of furniture, especially in designs where a clean, unobtrusive look is desired.
5. Industrial Equipment: Securing access panels and covers in machinery where regular maintenance checks are performed.
Captive screws are chosen for these applications due to their ability to stay in place, reducing the risk of loss and providing a convenient means of securement that can be easily managed by hand.
