We had 50,000 pcs of these custom 316L socket screws produced domestically for our action sports product customer.  Our goal was to recreate a 70 degree taper on the head profile originally accomplished using a machined secondary process.  The hardness of 316L stainless steel material made this is outcome difficult to achieve using a cold heading process.  After numerous test runs and adjustments the production team was able to achieve the desired result at last.
