This captive panel screw is a spring-loaded anti-loosening fastener specially designed for chassis, cabinets and panels. Made of stainless steel, it integrates three parts: knurled hand-turn head, spring and threaded sleeve. The screw is always connected with the sleeve and will not fall off or be lost after loosening. At the same time, it can be quickly tightened/loosened through the hand-turn head without additional tools. It is widely used in server cabinets, communication equipment chassis, electronic equipment panels, industrial control equipment and other scenarios, and is a special hardware for tool-free disassembly and assembly of panels with anti-loosening and anti-lost functions.
Key Features
