MS21250-02004 12-Point Flange Bolts

 

These MS21250-02004 12 point flange bolts were manufactured using domestic 8740 AMS 8322P steel material heat treated to AMS 2759/1 F AMS 2759 F to reach hardness of 40-43 HRC.  The parts were finished with CAD plating per AMS-QQ-P-416E specification, Type II Class 2.  Full certs were provided with the parts to our aerospace customer per order requirements.

Custom Oversize Brass Hex Nuts

 

These custom oversize brass hex nuts were manufactured using .661"-.669" across the flats brass bar stock material, measuring .764" across the corners.  They were tapped with 3/8-16 2B internal thread and chamfered on both sides.  The nut height was set to .500" +/-.015.  Samples were provided to our agricultural customer for testing prior to the full production order placement.

Custom Stainless Steel Torx Knurled Shoulder Screws

 

These custom stainless steel torx drive knurled shoulder screws were manufactured using 304 stainless steel material with factory passivated finish.  The shoulder measured 2.29-2.48MM X 19.05 +/- .12MM.  2-56 UNC 2A thread was incorporated at a length of 5.56 +0/-.5MM.  A T8 drive was cold formed and the outside of the head aggressively knurled for optimal finger grip.  A 180 degree nylon thread lock patch was applied over the threads to complete the production process.

Custom 440C Precision Machined Shaft Bushings

 

We had these custom 440C precision machined shaft bushings manufactured using DFARS compliant AMS 5830 material for our aerospace customer, with a passivated finish to ASTM A967.  The inside diameter on the bushings was set to .6255 +/- .0005" and outside diameter to .7528 +/-.0005", with a width of .185 +/-.002".  Full certs were provided with the parts, including a FAIR and NADCAP certified certs for all secondary processes involved in manufacturing the parts complete to print.

Custom Automotive 12-Point Flange Bolts With Zinc Flake Finish

 

We had these custom automotive 12-point flange bolts manufactured in grade 8 material (4140 alloy steel) with both low head and high head options.  1/2-13 2A thread was rolled on both version slightly undersized to allow for coating thickness of the Geomet zinc flake + top coat and black sealant.  Prior versions of the bolts our automotive customer used were experiencing failures from the hydrogen embrittlement resulting from the use of black zinc electroplating - black Geomet zinc flake coating was used to eliminate this risk and increase corrosion resistance at the same time.

Custom Stainless Steel Socket Shoulder Bolts

 

These custom stainless steel socket shoulder bolts were manufactured using 18-8 stainless steel material with factory passivation finish.  The head was fully cold formed, which took multiple tooling iterations to get just right.  1/4-20 2A thread was rolled at a length of .575" underneath the .305-.311" diameter shoulder.  A .190" across the flats hex socket drive was incorporated at a depth of .120" min.  Certs were made available to our customer's specifications.

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 Airframe Double Thread 17-4PH Precision Pins

 We had 4 different size variations of these custom airframe double thread 17-4PH precision pins manufactured for our aerospace and defense customer, with all production done domestically in the USA and the raw material DFARS compliant.  A combination of M6 X 1.0 and 10-32 UNJF rolled thread was required for each variation.  Lead time was the biggest challenge on these parts due to the rolled thread requirement and heat treat process but we managed to have all 4 parts completed within the requested timeframe.  Full certs were provided with the parts including a FAIR.

Custom Tamperproof NAS1352 Socket Head Pin-in Screws

 

Our aerospace customer needed NAS1352N04-06 socket head screws for their assembly but with a tamperproof pin-in socket head, which is not readily available off the shelf.  We had the pictured custom tamperproof version of this NAS1352 screw manufactured domestically to fully comply with the NAS specification using DFARS compliant material, with of-course the exception of the drive type.  Parts measured 4-40 X .375" and full certs were provided with the parts.

Custom DFARS A286 Aerospace NAS Socket Head Bolts

 

These custom DFARS compliant NAS1352N4LE16S socket head bolts were manufactured domestically for our aerospace customer using A286 stainless steel material from France.  They measured 1/4-20 X 1" and were finished with AMS2411 Rev J silver flash plating and bake, as well as thread locking patch.  Certification with mechanical testing performed per FF-S-86 specification were absolutely critical on these parts and were included together with material certs, passivation certs, and plating certs.
