Ball Lock Pins – Quick, Repeatable Locking for Precision Fits

Ball lock pins (often called quick-release or locking pins) are precision fasteners built to locate, align, and secure parts quickly and consistently. They’re a go-to choice for tooling, fixtures, industrial assembly, automotive, and aerospace applications where speed, safety, and repeatability matter.

At BAC-pins, we supply three proven styles to match different handling and retention needs: Double Acting R-Handle, Push Button B-Handle, and Detent Pins.

How It Works

1. Actuate the handle/button: The mechanism retracts the locking balls into the shank.
2. Insert the pin: Align the components and slide the pin through the hole pattern.
3. Release to lock: The balls expand automatically to secure the pin in place.
4. Remove in seconds: Re-actuate to disengage for fast, tool-free removal.
