Custom 8740 Steel Phil Flat NSN-53505-01-093-0290 & NSN-5305-01-093-2450 Screws

 

We provided our aerospace customer two variations of these custom 8740 steel phil flat screws, made using 8740 material per MIL-S-6049 with cadmium plating per QQ-P-416 Type I Class 2.  NSN-53505-01-093-0290 measured 10-32 X .713" while NSN-5305-01-093-2450 measured 10-32 X .837".  Both parts were manufactured domestically with full certs.  

Custom Extended Dog Point Set Screws

 

These custom extended dog point set screws were manufactured using 4140 alloy steel material with zinc clear finish.  6-32 thread was rolled at .150" in length and a 1/16" hex socket drive was incorporated.  Overall length measured .45" and the dog point diameter was set to .097 +/- .001".  Production lead time was 12 weeks from confirmed order and full certs were available upon request.

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 Invar 36 Socket Head Screws - 10-32 X 2"

 

These custom invar 36 socket head screws were manufactured domestically for University of Rochester with a broached socket drive for faster turnaround.  Invar 36 material is typically used in applications where dimensional changes must be limited or minimized in extreme temperature variations - thermal expansion is at a fraction of the typical carbon steels.  We have provided a number of parts in this material and often the socket head bolts incorporate a vent across the full length the part as well, depending on the exact application.  Full certs were provided with the parts.

Custom Precision Machined Components For Gun Manufacturers

 

We had 1,000 pieces of these custom precision machined components manufactured domestically in the USA to serve as housing parts in a defense article production application.  Aluminum alloy 2011 (Temper T3) material was used for the production and the parts were set for MIL-STD-171 compliant black dye.  Dimensional requirement were fairly precise with tolerance at +.000/-.001 for most specifications.  Full FAIR and documentation was included with the parts per customer requirements.

Custom Silicon Bronze Sleeve Bearings

 

We had 8 different configurations of these custom silicon bronze sleeve bearings manufactured domestically for our defense customer.  The inside diameter was set to .116" for all 8 different variations and the length was also consistently set to .125".  The outside diameter however varied from .180" to .210".  Production was done domestically in the USA and full certs were available upon request.  

Custom DFARS 316 Stainless Steel Screws

 

These custom DFARS 316 stainless steel screws were manufactured domestically with plain finish for our marine unmanned vehicle manufacturing customer.  The two sizes shown here are 8-32 X 7/18 and 10-32 X 5/8, both fully threaded.  The hex socket drive is broached on both sizes for fast turnaround - cold headed version provides better cost per piece but requires a longer lead time.  Full certs were provided with the parts.

Custom Domestic Alloy Steel Socket Head Screws - 10-32 X 1-3/8

 

These custom domestic alloy steel socket head screws were manufactured domestically for our customer that needed DFARS compliant 10-32 X 1-3/8 parts.  4140 alloy steel material was used, heat treated to Rc 37-44 and finished with black oxide.  All dimensions were per IFI standard and full certs were included with the parts.

Custom Full Thread Hanger Bolts - 5/16-18 Thread

 

We had 100,000 pieces of these custom full thread hanger bolts produced in grade 5 steel material per SAE J429 with zinc clear finish.  The overall length was at 3-1/2 inches with 1-1/2 inches of 5/16-18 machine screw thread.  The balance was rolled with 5/16-9 wood screw thread.  No unthreaded shoulder was incorporated with the parts per our customer's drawing requirements.  

Custom Long 316 Stainless Steel Screws

 

These custom long 316 stainless steel screws were manufactured domestically using a broached socket drive and cut threads to allow for the fast production turnaround required on the project.  The 316 stainless steel raw material was required to be DFARS compliant.  8-32 thread was incorporated at a length of approximately 1-1/8" and overall length underneath the head is 6".  All dimensions outside of the thread length were done per standard IFI dimensions.  Full certs were provided with the parts per customer request.
