The screw structure itself does not have an anti-falling function. The anti-falling function of the screw is realized through the connection with the connected part, that is, the small diameter thread of the screw is stuck on the mounting hole of the connected part through the corresponding structure to prevent falling off.
The spring loaded captive screw is composed of four parts: a hand-tightening sleeve, a riveting sleeve, a screw and a spring. Twist sleeves generally have straight knurled,we also called knurled Captive Thumb Screws.
