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 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.  

Custom 316 Stainless Captive Shoulder Screws - M4-0.7 Thread

These custom 316 stainless captive shoulder screws were manufactured domestically with plain finish.  The captive shoulder area measured 2.94MM X 12MM +/-.005" and the M4-0.7 thread covered 8MM of the overall length.  Slotted pan head was incorporated per standard IFI dimensions.  The metric thread on these parts was cut rather than rolled.

Custom 316 Stainless Steel Socket Head Screws

These are custom 316 stainless steel socket head cap screws at 10-32 X 1/2 and 10-32 X 3/8 in dimensions, manufactured domestically at a small batch of approximately 100 pieces.  The parts were completed in a relatively quick turnaround time-frame of approximately 4 weeks from order, especially considering the holiday timing.  To allow for the small quantity and speed the hex socket drive was broached instead of using a cold headed approach.  You can see evidence of this at the inside of the recess drive where you would see machining marks instead of the typical clean concave interior seen in cold headed parts.

Custom 316 Stainless Tapered Head Screws - 10-13 X 1.75" Thread Forming Screws With Gimlet Point & Custom Rounded Tapered Hex Head

These custom 316 stainless tapered head screws turned out to be a very tricky part - while the 10-13 thread and gimlet point were easy to incorporate, the custom head was a tough problem to solve.  A 10 degree taper was required on the hex flats and the corners rounded.  A rounded profile on a vertical cross-section of the head was also required to allow the screw to rotate while still maintaining hex head engagement.  It took three rounds of tooling to finally get the head shape just right and fit the application requirements our customer desired.  Domestic production of this part was set at 50,000 pcs with a lead time of 8-12 weeks.

Custom Metric Flange Bolts - Made Using 316 Stainless Steel Material

We supplied our industrial design customer these custom metric flange bolts in two different sizes, M12-1.75 X 35MM and M12 -1.75 X 45MM.  Small batch of 100 pieces in each length was manufactured using our overseas production facility as a test run to allow our customer to test the parts in their mold application prior to a full production run.  Due to the small quantities involved, the parts were machined rather than cold or hot headed.  The machining process is much faster because it avoids lengthy and costly tooling and machinery set up, which would not be cost effective for a small run.

Chrome Plated Phil Pan Hi-Lo Screws - 316 Stainless Steel Material With RoHS Compliant Tin Cobalt Finish, #10-16 X 3/4"

Another part to add to our growing list of custom tin cobalt and standard chrome plated fasteners.  These chrome plated phil pan hi-lo screws were manufactured overseas at approximately 50,000 pcs and supplied to our customer on a revolving blanket purchase order basis.  They measure #10-16 X 3/4" and are identical outside of the length to the #10-16 X 1/2 version we have supplied for a number of years already.  316 stainless steel material is used for optimal corrosion resistance, which is further enhanced with the chrome plating for use in highly corrosive environments.

Custom 6-Lobe Wood Screws - 316 Stainless Steel Material With Custom Shape Head

These are custom 6-lobe wood screws made in 316 stainless steel material measuring 1.888" in length +/- .005".  #10-13 thread tapping thread pitch is rolled after the custom shaped head is cold formed and T20 6-lobe drive incorporated.  Production is done domestically at approximately 50,000 pcs per run and the total quantity was provided to our customer in 2 batches with the first shipment containing 18,000 pcs.
