Locking L Pins

Alignment Pins

Product Information

Similar to a standard L Pin, 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. Available in pin diameters from 3/16 to 1/2" (6 to 12mm in metric), most in a choice of several pin lengths. Patent No. 3,471,186. Made in USA.

The complete assemblies listed below include a Locking L Pin, Locking-Pin Bushing, and Lockscrew. Choice of standard or long bushing in most sizes, for installation in thinner or thicker plates. Locking-Pin Bushings are designed to press fit in a standard reamed hole, and can be further secured with the included Lockscrew to positively hold the bushing in place.

Application Information

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