These are custom machine double end studs used for aerospace applications and in our case specifically for helicopter repair.  17-4 material is used and the 10-32 UNJF-3A thread is cut after the drilled hole process and machined operations are completed.  A 3/32 hex recess with a .225" deep cavity is created on one side using a drill and broach approach.  The drilled hole on the single threaded side measures .035 in diameter.

The parts were produced domestically in the USA with a lead time of approximately 8 weeks from order confirmation and were provided with full material certs, FAIR, and certificate of conformance.  Our internal part number is 11991.
