    Pull-Out Dowel Pins

    Remove pins even when you only have access to one end or they sit flush with the surface of your part. With one internally threaded end, they are easier to remove than most dowel pins. Thread a screw into the pin and then pull with the removal tool (sold separately). You can also pull the screw with pliers, but there’s more risk of damaging the hole.

    Single-End Studs

    Screw the threaded end of these studs into a tapped hole, and use the unthreaded end as a pivot point, hinge, shaft, or locator pin.
    Steel—These studs are steel for strength and wear resistance. They’re best for dry environments since moisture will cause them to rust. All meet ISO 2342 (formerly DIN 427), an international standard for fastener dimensions.

    Vented Pull-Out Dowel Pins

    Insert and remove from blind holes with less effort than pins that aren't vented. The vent relieves trapped air, so pressure doesn't create resistance as you install the pin. Because they have a tapped end, you can thread in a screw and pull the pin out with a removal tool (sold separately). You can also pull using pliers, but there’s more risk of damaging the hole.
    Flat Shaft
    Image of Product. Front orientation. Dowel Pins. Tapped Head, Standard Tolerance, Pull-Out Removal, Vented, Flat Shaft.
    The flat side of these pins creates a vent that's less likely to be blocked than a spiral shaft, but doesn’t offer quite as strong of a hold.
    Spring Steel—These pins won't deform from stress and vibration. They're stronger than stainless steel but not quite as strong as alloy steel. Pins perform best in dry environments since moisture will cause them to rust.
    18-8 Stainless Steel—The choice for wet and outdoor environments. In addition to resisting rust, these pins also withstand mild chemicals such as cleaners and degreasers. They are strong enough to join most components but won't withstand extreme stress and vibration as well as steel.

    Steel Headless Slotted Precision Shoulder Screws

    Image of Product. Front orientation. Shoulder Screws. Steel Headless Slotted Precision Shoulder Screws.
    With no head, you can flush mount these screws in countersunk holes and tight spaces. You can also use them as pins for aligning parts. They are engineered to tight tolerances for assemblies that require smooth and accurate movement, with shoulder diameters twice as precise as those on standard-fit screws. Hand-tighten with a slotted screwdriver to avoid damaging the drive.

    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 metric pins measures the overall length, including the thread.
    12L14 Carbon Steel—12L14 Carbon steel pins have good strength.
    Breaking Strength—Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.

    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.
