Precision locating pins with a large shoulder to resist downward forces. Tapered tip for easy part loading. The type shown here, with a press-fit shank, is designed for permanent installation (also available in a lockscrew type, with a slip-fit shank for renewable installation). Round Pins and Diamond Pins are often used together to locate from two holes in a work piece. Diamond pins are relieved, to locate only in 1 axis. Round Pins are also useful as side locators. Head and shank diameters are concentric to within .0005" TIR.
