What is a Hexagon Captive Countersunk Screw?
An Hexagon Captive Countersunk Screw is a fastener with the following characteristics:
Hexagon (Hex) Drive: The screw has a hexagonal socket in its head, designed for use with an Hexagon or Hex Wrench. This provides a secure grip for tightening and loosening.
Captive: The screw is designed to remain attached to a part or assembly, even when loosened, preventing loss during disassembly or maintenance.
Countersunk: The head is designed to sit below the surface of the material, creating a smooth and even finish without protrusion.
These screws are commonly used in industries like automotive, electronics, and machinery where secure fastening and repeated assembly/disassembly are important.
