Spring nuts, also known as spring-loaded screws or plunger screws, are specialized fasteners designed with an internal spring mechanism that provides consistent pressure or tension during operation. These screws are commonly used in mechanical assemblies where controlled movement, positioning, or load-bearing is essential. They help maintain pressure between components, absorb vibrations, and ensure secure contact. A typical spring nuts consists of a screw body, an internal spring, and sometimes a plunger tip. When tightened, the spring compresses to exert force, making it ideal for applications requiring repeated engagement or alignment. Spring screws are widely used in electronics, precision instruments, jigs, fixtures, and machinery setups where accuracy and reliability are crucial.
