Halder Ball Lock Pins | Precision Quick-Release Solutions | Freer Tool

Halder ball lock pins—often called quick‑release pins or detent pins—are used for fast, repeatable locating and retention in fixtures, tooling, and industrial equipment (application dependent). With a push-button or pull-handle action (style varies by listing), the locking balls engage to hold components in place, making ball lock pins a popular choice for setups that need frequent changeovers, adjustable positioning, or quick assembly/disassembly. They’re commonly used in fixture plates, jigs, automation equipment, guards, and modular tooling where speed and repeatability matter.

Self-Locking Pins Unlocked Without Tools by Press Button - Ball lock pins are self-locking pins. The balls are unlocked without tools by means of a press button. Often, ball lock pins are also called locking pin, safety pin or quick release pins. They can be used in many different industries and applications, such as fixing, locking, connecting, adjusting or for a quick change of positions. Ball lock pins are extremely resistant to shear and corrosion as well as they are optimally protected against wear.
