Custom Tapered Grade 5 Socket Head Screws - 10-32 Thread

 

We had these custom tapered grade 5 socket head screws produced for our sports product manufacturing customer with black oxide finish.  10-32 2A thread was rolled at a length of .36 +/- .03" and the head height was set to .14".  Head diameter was designed for .286" +/- .01" and a 1/8" hex socket drive was cold formed.  Our original production batch was sadly lost in transit with Fedex but we were able to push through to get replacement parts manufactured and delivered within 4 weeks to avoid a line shutdown with our customer.

Custom Grade 5 Hex Cap Screws - 5/16-24 X .875 With Black Oxide Finish

We have supplied these custom grade 5 hex cap screws to our customer for well over 10 years.  The parts are manufactured domestically, with production runs typically covering 50,000 pieces at a time.  The shoulder is critical on these parts, set at .312" in diameter +/- .005" and at 1/4" in length.  Head dimensions slightly off the standard for this size and the finish is black oxide and light oil.  Together with a number of other parts we supply these custom hex cap screws through revolving annual blanket purchase orders that split up the annual usage to match our customer's seasonality.

Custom Grade 5 Automotive Screws - Tricky 1/4-32 Thread With Nylon Thread Locking Patch

These custom grade 5 automotive screws are exactly the same dimensionally as the 1/4-28 version shown in one of the previous posts but with two specific distinctions: the thread had to be 1/4-32 instead for this 2,500 pcs batch and the lead time had to be FAST.  To accomplish this the hex socket drive was broached instead of cold heading, the marks of which you can see at the very bottom of the hex recess.  That allowed us to save weeks of lead time and we also expedited the thread lock application process as well as all the transit in between processes.  Level III PPAP paperwork is provided with the parts per our customers original request and requirement.

Custom Knurled Hardware - Test Knurling Samples For Custom 41L40 Steel Plate Bolts

Over the years we have provided countless custom knurled hardware pieces - below is a snapshot of a custom bolt we are working on producing for a customer that is intended to be hammered into a predrilled steel plate.  We noticed that the spec calls out for diamond knurling but realized that probably won't work for the intended purpose, which is to keep the bolt from spinning after being inserted.
