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.
Metric pins meet either DIN 6325-m6 specifications for steel pins or ISO 2338-m6 specifications for stainless steel pins. DIN 6325-m6 is functionally equivalent to DIN EN ISO 8734, with slight differences in hardness and length tolerances.
