    Threaded Taper Pins

    Image of ProductInUse. Tighten the nut to draw the pin out of the hole.. Front orientation. Contains Annotated. Taper Pins. Threaded Taper Pins.

    Tighten the

    nut to draw

    the pin out of

    the hole.

    Threads on these pins stick out for easy removal from blind holes. Tighten the hex nut to draw the pin out. Often used for positioning components and securing assemblies, they taper at a uniform rate to fit in tapered holes. For a snug fit, use a tapered drill bit that matches the pin number for inch sizes or the small end diameter for metric sizes. They have slightly rounded edges to aid insertion.

    Length for inch pins measures the unthreaded length of the pin.
    12L14 Carbon Steel—12L14 Carbon steel pins have good strength.
    ASME B18.8.2—Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions.
    Breaking Strength—Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.

    Round Head

    Diamond Head

    Screw the shank into a threaded hole for quick installation and removal. Mate these pins with holes in workpieces for precise alignment.
    Diamond Head—Diamond-head pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.

    Threaded Hole Location Gauges

    Image of Product. Back orientation. Threaded Hole Location Gauges.
    Find the true center of threaded holes to precisely align and measure parts. Once you thread these gauges into a hole, their cylinder sticks out as a reliable reference point. They’re often used with a coordinate measuring machine (CMM) to pinpoint the coordinates of the cylinder’s exact center. You can then use those coordinates to measure distances between points or reference them for error-free assembly. Even without a CMM, you can use these gauges with a micrometer to measure accurate center-to-center distances.
