Pull-Out Dowel Pins

One end of these pins is tapped, and the other is chamfered for easy insertion. To remove, thread a screw or tool into the tapped hole, then pull the pin out. Because they aren't vented, they work best in through holes. Use them as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. Pins are precision ground for accurate alignment. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Metric pins meet DIN 7979D-m6 specifications.
Steel pins have good strength.

Use with internally threaded dowel pins. A complete tool requires a puller handle and a tip that fits your pin. You’ll also need a socket head cap screw that can thread into the pin. To use, thread a tip into the puller handle and fit the other end of the tip over the screw. Slide the weight along the handle to push or pull.
Flat-Vent Pull-Out Dowel Pins

The flat side of these pins relieves trapped air, making them easier to insert and remove from blind holes. One end is tapped and the other is chamfered for easy insertion. To remove, thread a screw or tool into the tapped hole, then pull them out. Use them as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. Pins are precision ground for accurate alignment. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Metric pins meet DIN standards.
Steel pins have good strength.
Use puller handles, tips, and optional extensions (sold separately) with some internally threaded dowel pins to create insertion and removal tools. A complete tool requires a puller handle and a tip that fits your pin. You’ll also need a socket head cap screw that can thread into the pin. To use, thread a tip into the puller handle and fit the other end of the tip over the screw. Slide the weight along the handle to push or pull.

Threaded Taper Pins


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.
Breaking strength is measured as single shear, which is the force required to break the pin into two pieces.
Steel pins have good strength. Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions.
18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.
Length for metric pins measures the overall length, including the thread.

Metric Partially Threaded Studs

Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin. All can be installed and adjusted by hand or with a slotted screwdriver. 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.

Headless Alloy Steel Precision Shoulder Screws

Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount, or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components. With a shoulder diameter that is more precise than our general purpose shoulder screws, these screws are a good choice for measuring devices, optical fixtures, laboratory equipment, and other applications where precision matters. Made of alloy steel, they are strong and resist wear.
Metric screws meet DIN 927, an international standard for slotted shoulder screw dimensions.
