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.
Pins with a material certificate provide a traceable lot number and test report.
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.
Some pins meet material and dimensional standards set by ASME, Mil. Spec., DIN, or ISO.
