Types of Spring Loaded Pins

1. Ball Lock Pins

Ball lock pins are versatile locking devices used across various industries. They have a ball mechanism that engages with a hole in the receiving part, ensuring a secure hold. These pins are ideal for quick-change applications, allowing for fast and efficient assembly or disassembly.

2. Spring Plungers

Spring plungers are designed to provide a force that keeps them in place until pushed. They are widely utilized in indexing and locating applications, making them essential for precise alignment in machinery and fixtures. Their simple mechanism offers a reliable solution for many engineering challenges.

3. Detent Pins

Detent pins feature a spring-loaded ball that locks into a detent or groove, securing the pin in place. These are common in equipment assembly, where a temporary hold is necessary. Detent pins are often used in applications requiring quick adjustments or removals.

4. Pop Pins

Pop pins are designed for rapid release. They are commonly used in safety applications where quick access is necessary. Their mechanism allows for immediate disengagement, making them ideal for temporary fixtures and safety devices.

5. Latching Pins

Latching pins secure components using a latch mechanism. They are frequently found in automotive applications, such as securing hoods or doors. Their design ensures a strong hold while allowing for easy release when needed.

6. Retractable Pins

Retractable pins save space by retracting completely into their housing. This feature makes them perfect for applications where space is limited, such as in compact machinery or portable equipment.

7. Indexing Plungers

Indexing plungers are engineered for precise positioning. They are often used in tooling and machine setups, where they help to accurately locate parts before fastening.
