What are the common types of head designs for captive screws?

Captive screw, as an important fixing and connecting element, is designed with a variety of head designs to meet the needs of different application scenarios. Among them, common head design types include flat head, round head, with handle, hexagonal head, screwdriver slot, spherical head, and sealing ring. These designs not only differ in appearance, but also provide different options in terms of operability, ease of installation and removal.

Flat head captive screws have a flat top, allowing them to be flush with the equipment surface or panel, reducing protrusion and improving a neat appearance. The round head design is round, usually slightly protruding, but still relatively compact, providing a certain appearance and operability. Captive screws with handle design are easier to rotate and operate manually, especially suitable for occasions that require frequent installation and disassembly.

The head of the hexagonal head captive screw is hexagonal and is usually used with a hexagonal wrench to provide greater torque and more stable operation. The Captive screw designed with a screwdriver slot makes it easy to install and disassemble using a screwdriver or bit screwdriver. The captive screw with spherical head design has a spherical top and is used in applications that require large manual rotation.
