Dowel Pins
Use dowel pins as pivots, hinges, shafts, jigs, and fixtures to locate or hold parts. For a tight fit, your hole should be equal to or slightly smaller than the diameter shown. Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Steel pins are the strongest dowel pins. Steel pins are precision ground except for 1/32" diameter pins. Stainless steel pins are more corrosion resistant than steel pins. Pins that are passivated offer added protection against corrosion and oxidation. Stainless steel pins are precision ground except for 1/64" diameter pins. 416 stainless steel pins are more wear resistant than other stainless pins, but not as corrosion resistant. They are magnetic.

Vibration-Resistant Slotted Spring Pins
Interlocking teeth help these pins resist sliding when exposed to vibration. Also known as roll, tension, split, and expansion pins, they have a slot that presses closed when the pins are inserted so they don't flex after installation. Use them for fastening, pivoting, and holding.
Squeeze pins closed and install them in a hole slightly smaller than the pin. Tension holds them tight against the hole wall. The ends are chamfered to aid insertion.
Breaking strength is measured as double shear, which is the force required to break a pin into three pieces.
Pins are made of vanadium steel for excellent wear resistance.

Screw-Mount Locating and Support Buttons
Mount through the counterbored hole with a socket head cap screw to support and position workpieces and fixtures from the bottom or side. They’re also known as rest buttons.

Domed-Head Locating and Support Buttons
Support rounded or irregularly shaped workpieces from the bottom or side with minimal contact. Press the stud into a drilled hole for permanent installation. Also known as rest buttons.

Hole-Alignment Pins
Line up holes by driving these pins through existing rivet, pin, and bolt holes in multiple pieces of metal. Alternatively known as lineup taper punches.
Impact-Resistant Hole-Alignment Pins
Often called bull pins, these pins are designed to resist mushrooming caused by repeated pounding. The large striking surface allows you to drive the pins quickly and efficiently. Use alignment pins to align structural components such as I-beams and angle irons for bolting, riveting, and welding.
