    Round & Diamond Pins

    Round & Diamond Pins

    Locators

    These precision locating pins have a chamfered tip for easy part loading, and a shoulder to resist downward forces – important advantages over standard dowel pins. One Round Pin and one Diamond Pin are often used together to locate from two machined holes in a workpiece or to align two pieces of a fixture, without binding. Diamond Pins are relieved, to locate in only 1 axis. Round Pins are also extremely useful as side locators.

    Round Pins

    Round locating pins are precision engineered with a chamfered tip for easy part loading, and a shoulder to resist downward forces – important advantages over standard dowel pins. One Round locating Pin and one Diamond Pin are often used together to locate from two machined holes in a workpiece or to align two pieces of a fixture, without binding. Round Locating Pins are also extremely useful as side locators. Head and shank diameters on round locating pins are concentric to within 0.0005" TIR. Available with head diameters from 1/4 to 1" (6 to 20mm in metric). Carr Lane round locating pins are proudly made in the USA.

    Diamond Pins are available in three head-diameter tolerance ranges:
    X = Normal Tight Fit
    Y = Medium Fit
    Z = Loose Fit

    Application

    1. A series of locating pins can be used to locate a large diameter, instead of making a custom locating plug. In this example, three Round Pins are positioned 120° apart around the internal diameter of a large bored hole.
    2. 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 while loading and unloading the part, yet still maintains high accuracy.

    Material

    1144 steel, heat treated Rc 50-55, black oxide finish. DFARS and RoHS compliant.
