A photograph of the base of these strange brass pins. Notice the spring originating from the nut. Any thoughts?

Well - the verdict is in. Mr Jim Decker has told me that these are only part of an application - a variety of bracket known as a "Kindorf or Unistrut" channel. The spring on the nut is to hold the nut against the top of the channel. Thank you, Mr. Decker!
