What are Ball Lock Pins?

Ball lock pins are precision fasteners designed for quick, secure locking and easy release. Available in both single and double-acting variants, these pins provide reliable performance across various applications. Single acting ball lock pins feature a one-way mechanism, allowing easy insertion and secure locking without extra tools. Equipped with a push-button system, they engage locking balls that hold the pin in place. Double acting ball lock pins offer a two-way mechanism, enabling both secure insertion and quick release with a simple button press. Made from high-quality stainless steel, both pin types offer exceptional durability, corrosion resistance, and long-lasting reliability. Ideal for industrial, aerospace, and machinery setups, ball lock pins streamline operations, ensuring efficient fastening and quick adjustments.

What are MS Ball Lock Pins?

MS (Military Standard) ball lock pins that comply with stringent military specifications. The "MS" designation ensures that each pin meets the highest standards of quality and performance. Therefor, many other industries request for the MS standard.
