Product Information

Bullet-Nose Round Pins Part # CL-13-BND Carr Lane Mfg.®

Precision bullet-nose locating pin often used with a mating bushing to align two pieces of a fixture. One Bullet-Nose Round Pin and one Bullet-Nose Diamond Pin are often used together to locate two holes without binding, because the diamond version is relieved to locate in only 1 axis.

The pin's shank diameter and the bushing's OD are exactly the same size, to allow boring the installation hole in both fixture pieces at the same time for greater accuracy. The pin's head and shank diameters are concentric to within .0005" TIR. Available in pin diameters 1/4, 5/16, 3/8, 1/2, 3/4, and 1" (6, 8, 10, and 12mm in metric). Made in USA.

Application Information

Locating Principles

Diagram showcasing the application of Bullet Nose Round Pins

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.
