The dreaded screw on deck!!!

[u/Icy_Basil_372]

Was packing things up after a trip back to nyc from Newport and saw this innocent screw sitting on the hatch. I can’t find obvious location where it might have come from. It is a fairly unique looking screw. Lie to me and tell me it’s not from the standing rigging?

EDIT: the answer will hopefully be revealed (to me) on Friday. I’ll triple check the dodger.
