Product Description

Captive Screw/Bolt

  

Type:	Captive Screw/Bolt
Definition:	Captive Screws are a specialist fastener that is retained within a target assembly or housing, typically with an unthreaded portion below the head, called a reduced shank. The screw is captive meaning it cannot be totally removed from the hole or fall out when items are disassembled.
Description:	A captive fastener is a special type of screw that's able to lock into a pre-drilled hole to provide a secure and permanent hold. Like other screws, they feature a head on top and external threading on the sides. A Captive Screw is functionally the same as a standard screw, but features a specialized reduced shank, underneath the head of the screw.
Application:	Captive fasteners are used commonly in industrial machinery, where loose or lost screws can cause serious damage - particularly if a loose screw falls into a sensitive mechanism. Captive panel screws are designed to help keep parts to a minimum and eliminate risks associated with loose hardware that could fall out and damage components. Captive panel fasteners are ideal to attach metal panels or other thin material components in applications where subsequent access will be necessary.
Others:	How are captive screws inserted? Place fastener in hole on punched side of panel. Be sure the fastener shank or pilot is squarely within the hole before pressure is applied. Apply a steady squeezing force between press and anvil. Use sufficient force to embed the clinching ring around its entire circumference.
