Custom Grade 8 Offroad Wheel Bolts

 

These custom grade 8 wheel bolts were manufactured for our automotive OEM customer using SAE J429 material with zinc yellow finish with post plating bake.  An 82 degree countersunk feature was incorporated into the head with cold forging with 1/2-13 UNC 2B full thread below measuring 1.25" in length.  

Custom Stainless Steel UNEF Thread Precision Hex Nuts

 

These custom 3/4-10 UNEF stainless steel hex nuts were manufactured for our electronics customer using 304 stainless steel material.  They measured .938" across the flats and .375" in height with standard chamfers on both sides.  NADCAP certified passivation was completed to complete the parts for delivery.  Full certs were available with the parts as well as a Go/NoGo plug gauge.  We ran the samples of the part twice to ensure successful testing with the thread gauges.

Custom Torx Drive Grade 5 Titanium Screws

 

We supplied our high performance bicycle manufacturing customer these custom torx drive grade 5 titanium screws as an alternative to the traditional A4-80 material option.  The titanium material version offered great weight to strength ratio and also superior cosmetic options with the variety of anodizing colors.  The screws incorporated rolled M5 coarse thread at a length of .709" underneath the head.  The drive was cold formed on these parts and the balance of the head fully machined prior to thread roll.  Full certs were available with the parts.

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.
