Custom Precision Adapter Dowel Pins - 4140 Alloy Steel

 

These custom precision adapter dowel pins were manufactured for our defense customer using 4140 alloy steel material with Rc 38-42 hardness with plain finish.  Production was done in the USA and the pins measured .10800" +/- .00025" in diameter and .375" +/-.010" in overall length.  Full certs were provided with the parts per customer's instructions.

Custom Grade 5 3/4-10 Socket Head Flat Point Set Screws

 

We had approximately 6,000 of these custom 3/4-10 X 5 SAE J995 grade 5 socket head flat point set screws manufactured for our construction customer with zinc clear finish.  Overall length was set to 4.97-5.03" and the 3/8 hex drive was cold formed to a minimum depth of .375".  Lab tests were performed to confirm proof load of 85,000 psi min while maintaining core hardness of Rc 25-34.  Full certs were provided with the parts.

Custom Precision 304 Stainless Steel Small Dowel Pins

 

We had approximately 150,000 pieces of these small precision 304 stainless steel dowel pins manufactured for our customer with split scheduled releases.  The pins measured 2.93-3.42MM in overall length with a diameter of 2.390MM +0/-.002.  Slight 0.25MM radius was applied on both sides to complete the parts.  Commercial passivation was performed prior to sorting of the parts and material certs were provided with the parts, as well as our certificate of conformance.

Custom Precision Step Pins in 303 Stainless Steel

 

These custom precision step pins were manufactured domestically in the USA using 303 stainless steel material per ASTM A581, with the raw material comprising of 3/16" round USA melt bar stock.  The outside diameter is .031" +/- .002" for the extended pin and .125" +.0005/-.0000 for the main body.  Overall length was set to .313" and a 45 degree chamfer was incorporated on both sides of the .125" diameter portion.  Full certs were provided with the parts for our customer in the medical device manufacturing industry.

Custom Precision Tapered Pins In DFARS Stainless Steel Material

 

We supplied our aerospace customer with these custom precision tapered pins in DFARS stainless steel material, with production done domestically.  The pins were produced to an overall length of 0.765" and tapered from .125" max to .110" on the narrower end.  A .020" wide slot was incorporated at a depth of .135".  Full certs were provided with the parts per customer requirements. 

Custom Metric Shoulder Bolts - 304 Stainless Steel

 These custom metric shoulder bolts were manufactured using 304 stainless steel material with the head cold formed and shoulder machined to a diameter of 11.965-11.938mm by 80mm in length, with 16mm of M10 X 1.5 6g thread after the relief.  The knurled socket head incorporated a 6MM hex socket drive.  Material certs and a certificate of conformance was provided with the parts.

Custom Slotted Pins - DFARS Stainless Steel

 

We had these custom slotted pins manufactured domestically for our aerospace customer using DFARS compliant 303 stainless steel material.  The pins measure .094" in diameter and .35" in overall length, with the slot at .020" in width by .115" in depth.  The outside profile tapered from .094" diameter max to .088" at the narrow side.  Full certs were provided with the parts.

Custom Flat Stamped Nuts - M8-1.25 Thread

 

We had slightly over 10,000 pieces of the custom flat stamped nuts manufactured using mild steel material with zinc clear finish.  Outside dimensions measured 22.86mm X 16mm with thickness set to 6mm.  M8-1.25 6h thread was tapped with its center approximately 5.6mm from the edge of the nut.  6mm is probably the maximum thickness to allow stamping for this size nut without exhibiting too much variation in thickness along the profile.

Custom Precision Cam Nuts - Mild Steel With Zinc Plating

 

We had 12,000 pieces of these large custom precision cam nuts manufactured in mild steel for our construction component manufacturer.  Overall length measured 91.7MM and max OD at the base was set to 23.88MM.  M8 X 1.25 6g thread was incorporated on both sides and M12 X 1.75 6h thread was tapped in the center of the base.  Both shoulders were tuned to a 13.37-13.48MM diameter.  Material certs and certificate of conformance was provided with the parts.

Custom Bent Steel Zinc Washers - Mild Steel With Zinc Plating

 

These custom bent steel zinc washers were manufactured for our specialty OEM manufacturer using mild steel ranging in thickness from 1.8-2.0MM - the edges of the bent washer are actually used to clamp down the assembly so the thickness had to be just right to allow the application of the needed force without flattening out.  The top level dimensions of the rectangular shape are 23.7 X 44.8MM with a +/-.5MM tolerance and the inside drilled hole measures 8.5MM in diameter.  The outside height of the component is set to 7.34MM.  A simple part but it took us 3 sets of samples and tooling variations to get it to perform exactly as required.
