Project Description

We had 500 pieces of these large custom locating dowel pins manufactured domestically in alloy steel material, with heat treat to achieve 47-58 HRC core hardness. The original drawings were fairly aged and it was difficult to figure out how the transition point between the round and hex portions of the pins should be formed. We ended up producing samples with two different alternative interpretations and allow the customer to test for the ideal option pictured here. The round portion of the pin has a diameter of .625″ + .0003″/-0″ while the hex portion across the flats had to meet .7497 +.0002″/-0″. Overall length was set to 1.4375″. Full certs with FAIR were available with the parts.
