For those who wonder what the VS stands for - the answer is VOI-SHAN a long time supplier of aerospace standard fasteners.
The HL1013- 6 means simply a 6AL-4V TITANIUM FASTENER 6/32 DIA ( 3/16 )
Thousands of those in 3/16 to 3/8 diameter have been used on most every model and manufacturer of airplanes or missiles for decades. They are batch inspected and certified, and carry NO serial or batch number.
I mention this only to tamp down the ' can we trace that fastener to a particular part or airplane or location ?"
The answer is NO (absent ID of surrounding part(s) )-
There is Nothing unique about that particular fastener oher than its material compared to others of high strength steel (s).
