Captive Screws Captive panel fastener Screw

Captive screw is also known as a non loosening screw or an anti loosening screw. Everyone has different habitual names, but in fact, the meaning is the same. It is achieved by adding a small diameter screw and relying on the small diameter screw to hang the screw onto the connecting piece (or through a clamp or spring) to prevent the screw from falling off. The screw structure itself does not have the function of preventing detachment. The anti detachment function of the screw is achieved by the connection method with the connected part, that is, by clamping the small diameter screw of the screw onto the installation hole of the connected part through the corresponding structure to prevent detachment.

The front of the non loosening screw is a thread, and the middle is a thin screw, which is cleverly used to prevent detachment. It is mainly divided into the following categories: slotted pan head captive screws, hexagonal socket head captive screws , knurled head captive screws , slotted countersunk head captive screws.
