Engineered Precision: Ball Lock Pins for Rapid & Secure Fastening
Our Ball Lock Pins (also known as Positive Lock Pins) are the pinnacle of quick-release technology. Unlike simple detent pins, these Push Button Pins provide a mechanical lock that cannot be released until the button is depressed. This ensures that the pin remains securely in place even under extreme vibration or lateral loads. Designed for the most demanding environments, our pins are the go-to solution for aerospace ground support, racing pit equipment, and precision jigs.
We specialize in 17-4 PH Stainless Steel Ball Lock Pins, which are precipitation-hardened to provide the highest shear strength-to-weight ratio in the industry.
Ergonomic Handle Options
Select the right handle for your operational requirements:
T-Handle & L-Handle
Offers maximum leverage and a firm grip for operators wearing gloves. Best for heavy industrial machinery.
Button Handle
Compact and snag-free. Ideal for tight spaces where accidental release must be avoided.
Ring Handle
Optimized for use with Lanyards and Tethers, ensuring the pin stays with the equipment at all times.

Ball Lock Pins FAQ
Q: Why is 17-4 PH Stainless Steel preferred for Ball Lock Pins?
A: 17-4 PH is a precipitation-hardening alloy that offers a rare combination of high hardness (preventing wear on the balls and shank) and high tensile strength, while maintaining excellent corrosion resistance.
Q: Can these pins be used for lifting?
A: While Ball Lock Pins have high shear strength, they are generally not rated for overhead lifting unless specifically certified as Lifting Pins. Always verify the safety factor for your specific application.
Q: Do you offer customized Grip Lengths?
A: Yes! As a professional fastener manufacturer, we can produce custom grip lengths (L dimension) to within +/- 0.5mm to ensure a perfect fit for your fixture.
