Custom Stainless Steel Step Down Precision Pins

 

We provided these custom stainless steel step down precision pins to our utilities customer.  It took a few iterations of the design and specifications to dial in the drawing and we then produced these parts using 18-8 stainless steel material with plain finish.  Prior to our production our customer was manually assembling this part using the 3 individual components and we eliminated that cumbersome process by providing a single fully machined version.

Custom 17-4PH Precision Dowel Pins With Spherical Points

 

We supplied our customer that manufactures fire pump equipment with these custom 17-4ph precision dowel pins using 100% domestic production with DFARS compliant raw material and full certs - material certs, heat treat certs, and a certificate of conformance.  The pins were produced to a diameter of .1249-.1251" and overall length of .670-.675" with equal spherical radii on both sides.  Parts went through heat treatment to achieve the Rc36 hardness minimum requirement.  

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.
