Custom Steel Slider Lock Pins With Cotter Pin

 

These custom machined steel post pins were manufactured using low carbon steel with plain finish.  The head measured .41" in diameter and the shoulder .200" with a .063 thru hole for the cotter pin.  The pins measured .60" in overall length underneath the head.  Cotter pin and washer used for the full assembly at application were also custom made to drawing for our electronics customer.

Custom Locating Dowel Pins For Gear Units

 

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.
