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.
At Dongguan Sango Hardware Fasteners Co., Ltd., we design and manufacture detent pins for global clients across automation, aerospace, tooling, and heavy machinery industries.
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
2. Types of Quick Release Detent Pins
🔹 Button-Head Detent Pin
- Push-button releases the locking balls
- Most secure and ergonomic option
- Used in jigs, frames, and machine bases
🔹 T-Handle Detent Pin
- T-shaped grip allows strong pull force
- Ideal for gloved operation or high-retention loads
🔹 Ring Pull Detent Pin
- Compact, low-profile design
- Suitable for tight access areas
🔹 Double-Ball Detent Pin
- Two or more locking balls for increased holding power
- Used in safety-critical or high-vibration environments
🔹 Cable-Retained Detent Pin
- Pin is tethered to fixture or housing
- Prevents loss or misplacement during maintenance
3. Applications of Detent Pins
Quick-release detent pins are vital in systems requiring frequent changeover or flexible positioning:
- 🛠️ Workholding and modular fixturing
- 🤖 Robot end effectors and tool changers
- 🛫 Aircraft service carts and panel access
- 🚛 Vehicle ramps, trailers, and tow bars
- 🎮 Fitness equipment with adjustable resistance
- 📦 Packaging machines and adjustable guides
They replace traditional bolts or cotter pins where speed and ergonomics matter.
4. Choosing the Right Detent Pin
