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.
We supply these charcoal painted truss head screws on a revolving blanket purchase order basis, with annual usage at approximately 100K pieces. The truss head screws measure 14-10 X 1-3/4 with type A sheet metal screw thread. The large sharp threads on these screws, combined with the large surface area of the truss head, make these parts very difficult to handle. Without extra care in packaging, with layers of protection between every 1,000 pcs or so, the painted head gets scratched enough to cause cosmetic issues.
