53LEDSLED said:its to hold 2 pieces of flat (or kinda flat) sheet metal together while keeping them flush and close together (0.0299" ~ 22 gage) it works really good.
what i did was cut the the threaded rod just long enough to grip onto the wing nut and then mark it in the middle with a cut-off saw. i used the mark to start cutting it down the middle with a hacksaw (it has a thin blade so the 22 gage metal will fit perfect) i then spot welded a small piece of 22 gage metal to it and bend the bottom part.
Harbor Freight sells them for I thing 4 for about $5.00. But I did not see them on the counter and asked and they were behind the counter by the welding stuff. Ed ke6bnl
