Carr Lane CL-186-RPT | 3/16" Diameter x 5/16" Shank Steel Black Oxide Coated Round Locating Pin

Round Locating Pins

One Round Locating Pin and one Diamond Locating Pin are often used together to locate from two holes without binding, because the Diamond Locating Pin is relieved to locate in only 1 axis. The type with a press-fit shank, is designed for permanent installation. Head and shank diameters are concentric to within 0.0005" TIR. Made in USA.

Application Information

A series of locating pins can take the place of a locating plug. The pins are positioned at three points, 120 degrees apart, around the internal diameter of the hole. This arrangement is usually much more economical than making a custom plug.

Foolproofing prevents improper loading of a workpiece. The problem is most prevalent with parts that are symmetrical or located concentrically. The simplest way to foolproof a workholder is to position one or two pins in a location that ensures correct orientation.

Locating Principles

When a round pin and diamond pin are used together, the round pin is the primary, 2-axis locator, while the diamond pin is the secondary, 1-axis locator. Diamond pins are relieved to locate only radially around the round pin, avoiding redundant location. This prevents binding, yet still maintains high accuracy.
