Quick Release Pins: Fast, Reliable, and Tool-Free Locking for Industrial Applications

When working with modular fixtures, jigs, automated machinery, or adjustable components, one question comes up repeatedly:

How can we quickly lock or release a component without tools—while keeping it secure and repeatable?

The answer lies in the versatile and robust Quick Release Pin, also known as a Ball Lock Pin or Fast Lock Pin. At Dongguan Sango Hardware Fasteners Co., Ltd., we specialize in the manufacturing and customization of these high-performance components.

This article covers everything you need to know about Quick Release Pins—their structure, applications, material choices, and how to select the right type for your project.

1. What Is a Quick Release Pin?

A Quick Release Pin is a mechanical fastener designed to connect, locate, and lock parts in place without the need for tools. The user can insert and remove the pin by hand, allowing fast, repeatable operations in high-cycle industrial environments.

Most quick release pins consist of:

• A pin shaft (various lengths and diameters)
• A locking mechanism (usually spring-loaded balls)
• A head for manual operation (button, T-handle, ring, or L-handle)

2. Common Types of Quick Release Pins

🔹 Push Button Ball Lock Pin

• Push to release spring-loaded balls
• Inserted and automatically locked into mating holes
• Best for quick-change fixtures and repetitive operations

🔹 T-Handle or L-Handle Quick Release Pin

• Ergonomic handle for easier grip and greater torque
• Suitable for large equipment, glove-wearing environments

🔹 Ring Pull Pin

• Ideal for confined spaces where a button can’t be pressed
• Easily operated with a finger or tool

🔹 Detent Pin

• Uses a small spring-loaded ball or plunger, no button
• Simpler, lower-cost solution for low-load positioning

🔹 Heavy Duty Quick Release Pin

• Reinforced shaft, higher shear load ratings
• Used in aircraft tooling, construction equipment, and high-force applications

3. Use Cases and Applications

Quick release pins are used across various industries:

• Manufacturing jigs and fixture systems
• Robotics and modular work cells
• Adjustable gym equipment
• Medical device platforms
• Aerospace and automotive assembly
• Military ground equipment and transport structures

🔧 At Sango Hardware, we manufacture standard and custom pins to meet industry-specific requirements.
