    Taper Pins

    Often used for positioning components and securing assemblies, these pins taper at a uniform rate to fit snugly in tapered holes. They have slightly rounded edges to aid insertion. To install, create a tapered hole using a taper-pin drill bit that matches the pin number for inch sizes or the small end diameter for metric. To remove, hit the small end of the pin with a punch to drive it out.

    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.

    These internally threaded pins sit flush in an assembly. For easy removal from a blind hole, thread a screw into the pin and pull out. Often used for positioning components and securing assemblies, they taper at a uniform rate to fit in tapered holes. Use a tapered drill bit that matches the pin number for a snug fit.
