• Locking Clamping Pins are similar to standard Clamping Pins, except that the pin body is positively retained in a locking bushing. In fully retracted position, the bushing's spring clip snaps into the pin's radial groove. This holds the pin fully retracted by spring force and positively prevents removal. Spring pressure also holds the pin in intermediate extended positions, an advantage especially if the fixture is turned upside down.

• These threaded alignment pins can be used for locating and clamping, or for clamping only, depending on extended screw length. The upper bushing is furnished separate from the pin, and must be welded in place at the proper length to suit the application. Available in thread sizes from 1/4-20 to 1/2-13 (M6 to M12 in metric). Made in USA.

Application: In fully retracted position, the bushing's spring clip holds the Clamping Pin fully retracted by spring force and positively prevents removal. Spring pressure also holds the pin in intermediate extended positions.

This pins are available in diameters of ¼” to ½”.
