The adapter on the attached pic is for using an Ikelite strobe with ULCS and similar strobe arms. I want to use it in a DIY project and need a screw nut for it.
All I know is that the thread is definitively not metric... Could someone please help and provide the specifications (like UNC 1/2")? Thanks!
