    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.

    Tapped Taper Pins

    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. They have slightly rounded edges to aid insertion.
    12L14 Carbon Steel—12L14 Carbon steel pins have good strength.
    ASME B18.8.2—Pins meet ASME B18.8.2 specifications for material and dimensions.

    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.
