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.

Metric Threaded on One End 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.
