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.
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. 18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic.
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.
DIN 7 is no longer an active specification and is superseded by ISO 2338-m6. They are functionally equivalent with slight differences in length and the pin ends. DIN 7 has rounded ends where ISO 2338-m6 has chamfered ends.
