Custom 6-Lobe (Torx Alternative) Shoulder Screws in 416 Stainless Steel

 

We had these custom 6-lobe shoulder screws manufactured in 416 stainless steel in the USA for our electronics customer.  DFARS compliant material was used and the parts were heat treated to achieve 26-32 RC.  The 6-lobe drive (T10 size) was made using a combination of broaching and punch, allowing us to bypass cold forming that carries a much longer lead time in our current conditions.  The shoulder measures .13" X .500" in length and the threaded portion is #4-40 with a minimal undercut.  Full certs were included with the parts per our customers requirements.

Custom Low Profile Socket Head Screws - 302 Stainless Steel With 6 Lobe Drive

These custom low profile socket head screws with a  6-lobe (torx) drive were manufactured domestically using 302 stainless steel material with a commercial passivated plain finish.  5,000 pieces of two sizes were produced: M10 - 1.5M X 65MM with a T-45 drive size and M8 - 1.25M X 65MM with a T-30 drive size.  26-30MM of thread was incorporated on the larger version and 22-25MM on the smaller diameter part.  The low profile & 6-lobe drive combination is relatively tricky, especially for these larger diameters as additional controls in tooling are required to avoid flowering on the outside profile of the head.

Custom Low Profile Torx Machine Screws - 18-8 Stainless Steel

These custom low profile torx machine screws were manufactured domestically using 18-8 stainless steel material, at production volume of approximately 5,500 pieces.  T10 size 6 lobe drive was incorporated and the head diameter at .262" +/-.01" and head height at .263" +/-.01.  6-32 thread was selected for the .185" of thread, followed by a lead point measuring .090" +.000/-.002 in diameter and .050" +.020/-.000 in length.  Parts were passivated per MIL QQ-P-35 Type II to complete the production process.

Custom 6-Lobe Socket Head Cap Screws - 6-32 X 1-1/4 In 18-8 Stainless Steel Material

Custom 6-lobe socket head cap screws manufactured domestically in 18-8 stainless steel material at approximately 8,000 pcs.  Our customer wanted us to provide these custom screws in black oxide finish after running them through ASTM A967 passivation.  Partial unthreaded shoulder was incorporated and the thread was rolled instead of the cut alternative.  Lead time for similar projects is currently running at 8-12 weeks from order confirmation.

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.

Custom 6-Lobe Socket Cap Screws - 4037 Alloy Steel Heat Treated Material

These are custom 6-lobe socket cap screws made domestically using 4037 alloy steel material.  Strength was absolutely critical to our customer and the parts were heat treated to 39-43 hrc. In the absence of an available drawing for this part we had to work off samples our customer provided for all dimensional attributes.  After confirming the material, strength, and dimensional requirements we had 1,000 pcs produced for our customer with a lead time of approximately 12 weeks from order confirmation.  Heat treat and material certs were included with the parts.
