FEATURES: Precision locating pins with a tapered tip for easy part loading, and a shoulder to resist downward forces (superior to standard dowel pins). Round Pins and Diamond Pins are often used together to locate from two holes in a workpiece. 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. Made in USA.
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 while loading and unloading the part, yet still maintains high accuracy.
