Quick Release Pins for Fast, Tool-Free Assembly and Positioning in Mechanical Systems

In high-efficiency industrial settings, the ability to quickly assemble, disassemble, and reposition components can dramatically reduce downtime and enhance productivity. Quick Release Pins provide an ideal solution—offering secure fastening and tool-free operation for a wide range of mechanical systems.

At Dongguan Sango Hardware Fasteners Co., Ltd., we design and produce precision quick release pins engineered for aerospace, manufacturing, automation, and fixture systems, where speed, strength, and reliability are essential.

1. What Is a Quick Release Pin?

A Quick Release Pin is a removable fastening device that locks into place using a spring-loaded ball, push button, or detent mechanism. Designed for frequent removal or adjustment, these pins enable rapid, repeatable connections between components—without tools.

🔩 Key Benefits:

• Fast installation and removal without tools
• Positive locking to prevent accidental disengagement
• Ideal for modular systems, fixtures, and positioning applications
• Available in various diameters, grip lengths, and locking styles
• Suitable for heavy loads and high-cycle use

2. Common Types of Quick Release Pins

🔹 Ball Lock Pin (Push Button)

• Features a push button that retracts ball bearings to release the pin
• Used in aircraft, mold setups, and quick change tooling

🔹 L-Handle or T-Handle Pin

• Provides a large grip surface for manual operation
• Ideal for tooling jigs, machine adjustments, and workholding setups

🔹 Detent Pin (Spring Ball)

• Uses spring-loaded balls to hold the pin in place once inserted
• Common in transport equipment, display systems, and equipment racks

🔹 Double Acting Pin

• Retracts on both ends and allows pin release from either side
• Used in tight spaces or dual-access assemblies

🔹 Ring Handle Quick Release Pin

• Allows pull-to-release function using a key ring-style loop
• Common in military equipment, scaffold locking, and portable fixtures

3. Applications of Quick Release Pins

Quick release pins are used in applications that demand frequent adjustment, rapid installation, and high holding strength:

• 🏗 Automation equipment and robotics (end effectors, indexing tables)
• ✈️ Aerospace tooling and ground support equipment
• 🧰 Jigs and fixtures in CNC machining centers
• 🚜 Agricultural and construction equipment (pivot arms, blade locks)
• 🧪 Medical and diagnostic equipment (quick-change mounts)
• 🧳 Sports and outdoor gear (bike racks, folding systems)

These pins reduce downtime, minimize the need for tools, and enhance assembly efficiency.

4. Material and Finish Options

Finish options:

• Polished stainless for corrosion protection and aesthetics
• Black oxide for low glare, mild corrosion resistance
• Zinc plating for industrial applications
• Anodized aluminum for color coding or visual identification
• Passivation for enhanced stainless steel durability
