Captive fasteners are a specialized fastener type, capable of achieving a permanent hold of an assembly even during servicing procedures. Captive fasteners can create a hold through a number of methods, taking advantage of thread locking, press-fitting, or broaching for ample security. Additionally, some captive fasteners may even meld with the material they are joined to if welding or cold forming is carried out. To best understand how captive fasteners can be beneficial for various applications, we will discuss some of the most common types that may be used for installations.
