AH0021-A4 Captive Screws Hexagon Socket Cap Head 
stainless steel 316 

A captive screw is a type of fastener designed to remain attached to a component, even when loosened. It typically has a threaded shank and a head, ensuring it doesn't fully detach from the object it secures. This design helps prevent loss or misplacement of the screw during maintenance or assembly.
