The production of these custom long compression springs in 17-7PH material was run at a relatively small batch of only 25 pieces. 17-7PH material was used per AMS 5678 and all production work was done domestically with all secondary processes done with NADCAP certified facilities. A first article inspection report (FAIR) was provided as well with the parts together with all other certs. .060 +/-.0015" diameter wire was used to make this part and the ID/OD was set to .78"/.90". Parts were passivated per AMS 2700, method 1, type 2 or 8 with full certs to complete the production process spanning approximately 7-8 weeks from start.
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.
Production of these custom internally and externally threaded studs was run at approximately 10,000 pieces, in medium carbon grade 5 equivalent steel material. The specific hardness requirement was set to 25-35 HRC. The custom threaded studs had an overall length of .75" +/.02" with a 45-50 degree tapered point on one side. Slotted drives were incorporated at both sides for optimal flexibility in our customer's application. 1/2-13 thread was rolled on the outside and 1/4-20 thread tapped all the way through.
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.
These custom flange nuts were manufactured domestically using 17-4PH stainless steel material with 10-24 internal thread. Overall height of the flange nut was .19" +/-.01" and the diameter of the flange was a critical dimension at .330" +.000/-.015". The hex was set to .250" +.000/-.005" across the flats. Our internal part number is NRNS-10-117-4 and typical lead time for full production is 6-8 weeks from order confirmation.
