Custom Long 316 Stainless Steel Screws - 8-32 X 3 Socket Head Cap Screws

Custom Long 316 Stainless Steel Screws - 8-32 X 3 Socket Head Cap Screws
These are custom long 316 stainless steel screws at 8-32 X 3 in dimensions, manufactured domestically at a small batch of approximately 40 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.  The partial thread was also cut rather than rolled to allow for the short production run option.
