Quick Release Detent Pins for Modular Fixtures and Fast Tool Change

When time is money, and every second counts during setup, adjustment, or part changeover, you need fasteners that are secure, repeatable, and tool-free. Enter the Quick Release Detent Pin—a compact, spring-loaded solution for instant engagement and release in a wide range of industrial environments.

1. What Is a Quick Release Detent Pin?

A Quick Release Detent Pin is a mechanical pin with one or more spring-loaded balls near the tip. These balls snap into position when inserted into a hole or fixture and hold the pin in place until pulled out with force or a handle.

🔩 Key Features:

• Tool-free locking and unlocking
• Retention via ball detent system
• Rapid installation and removal
• Reusable across thousands of cycles
• Optional lanyard or tether for retention

3. Applications of Detent Pins

Quick-release detent pins are vital in systems requiring frequent changeover or flexible positioning:
