    Slotted Bushings

    Image of ProductInUse. Front orientation. Contains Annotated, Inset, MultipleImages. Slotted Bushings.
    When locating a workpiece using through-hole alignment pins (sold separately), use one of these bushings and one standard bushing to prevent the pins from binding in your fixture. One pin sits in the standard drill bushing for tight-tolerance locating in all directions, and the other pin sits in the slotted bushing for tight-tolerance locating in only one direction. This functionality is similar to the combination of round and diamond-head locating pins. Press these bushings into a drilled hole for permanent installation. They’re also known as slotted locator bushings.
    Slotted Bushings with Etched Line—Check the position of the markings to make sure your bushings are aligned.
    Slotted Bushings with Spring Pin—A spring pin helps you align bushings and keep them from rotating. To mount in your fixture, drill one hole for the spring pin, then another for the bushing.

    With a knurled surface, these bushings grip plastic workpieces tightly so they don't wobble or slip. Use them to prevent through-hole alignment pins (sold separately) from binding while locating workpieces. Your first pin sits in one of these slotted bushings for precise locating in one direction. The second pin sits in a standard bushing for locating in every direction. This setup is similar to the pairing of round and diamond-head locating pins. They're also known as slotted locator bushings.
