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 Stainless Vented Pins - 303 Stainless Steel

 These custom stainless vented pins were manufactured domestically using 303 stainless steel material and measure .393" +/-.01 in overall length with 3/8-24 partial thread.  They are fully vented with an ID of .124 +.002/-.000.  A slotted drive (.03" across) was incorporated on the threaded side and the parts were completed with a passivated finish per MIL QQ-P-35 Type II.  Full certs were provided with the parts to comply with our customer's requirements.  

Custom Internally Threaded Square Pins - 12L14 Steel Material

 

These custom internally threaded square pins were manufactured using 12L14 square bar stock material - sharp corners were absolutely critical and initial trial runs with alternative material options were unsuccessful until we finally found square bar material measuring very close to .69" across the corners.  The sharp corners allow the pins to lock at the remaining .14" long shoulder seen on the parts.  Both machined sides of the pins tightly fit into mating parts in the assembly.  Production was done at 25,000 pieces, with overall length at 2.25" and 1/4-20 internal thread on one side.  

Custom Precision Dowel Pins In 18-8 Stainless Steel Material

We had 3,200 pieces of these custom precision dowel pins made domestically for our medical device customer using 18-8 stainless steel material with plain finish.  Overall length was set to .240" +/- .005" and the diameter was set to .092" +/-.005".  These were relatively simple parts and the lead time was much faster than the more involved parts that require a special finish.  Full certs were provided with the parts.

Custom Precision Steel Pins - 1018 CRS Material

These custom precision steel pins were manufactured domestically for our customer involved in water treatment product manufacturing.  1018 CRS material was used with plain finish.  The drive-less head measures .060" in height and .290" for the diameter, +/-.005".  The shoulder portion was the most critical with a diameter of .195" +/- .001" and a slight 45 deg by .02" chamfer.  Overall length of the shoulder shaft was set to .460".  Production is typically done at 5,000 pieces at a time.

Custom 17-4PH Dowel Pins - 5MM X 22.8MM In DFARS 17-4PH Material

These custom 17-4PH dowel pins were manufactured domestically at 6,000 pieces.  DFARS 17-4PH stainless steel material was used, per AMS5622 with H900 heat treatment required.  Overall length was 22.8MM +0/-.4 and the critical diameter of the pins measured 5MM +0/-.013.  Our internal part number for this custom dowel pin is 12901978 and typical lead time is 12-14 weeks from order confirmation.

Custom Threaded Stainless Pins - M3 & 10-32 Thread

These are tiered custom threaded stainless pins created for an audio equipment manufacturer in 18-8 stainless steel material.  Production was done domestically with a lead time of 5-6 weeks from order.  The overall length of the part is at 1.4" inclusive of .90" of M3 coarse thread and .37" of 10-32 thread.  Multiple shoulder steps were incorporated per our customer's specifications and the drive-less head measures .50" for the OD and .066" for the height.  The next iteration of this part will likely incorporate a thicker head and a slotted drive.

Custom Stainless Steel Precision Pins - 303 Stainless Per AMS 5640 V Type 1

220 pieces of these custom stainless steel precision pins were produced domestically for our aerospace customer using 303 stainless steel material.  Original specifications on the drawing called out for 303 stainless steel per AMS 5638 but we obtained a deviation approval to provide the part using a similar AMS 5640 V Type 1A spec material instead.  Passivation per AMS 2700, method 1, type 4, class 2 was done to complete the parts prior to QC inspection.  Overall length measures at 1.131" +/-.005 and the shaft diameter is set to .074-.075".  The width of the flattened section on one end reaches a diameter of .084" +/- .005.  The other end is rounded at R .078.
