Specification
Captive screws are also called captive panel screws, or captive bolts. It features a small-diameter thread, relying on the small-diameter thread to hang the screw on the connecting piece (or through the clamping sleeve and clamping spring) to prevent the screw from falling off. 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.
How to Install Spring Loaded Captive Thumb Screws?
- Place the captive screws into the grooved base fixture
- Drill the installation holes of the corresponding size on the plate and make the holes
- Lay the panel on top of the spring-loaded captive screws
- Adjust the relevant parameters of the riveting equipment, press evenly, and make the positioning ring expand
- The reduced diameter section is reached, retaining the screw on the panel and the installation is completed.
