I have this bracket and I'm trying to put it on two different light stands. The stud on this one fits perfectly: (it's a Westcott 9910 stand). The socket slides all the way down on the stud so when the screw is tightened it is straight and very secure. Here's a picture of it fitting:
However, the stud on this one seems about the same, but basically doesn't fit: (it's this Impact LS_CS40M-40 stand). The socket slides most of the way down, but it doesn't "seat" at the bottom, so when I tighten the screw it lean sideways and doesn't seem at all secure. Here is a picture of the "lean" that is induced: and a clear explanation of the problem - that the bracket is not reaching the larger diameter part of the stud at the bottom:
Do these studs have different names? Is there an adapter I can get for the one that doesn't fit to make it fit the bracket? Or should I get a different bracket to match the stud directly?
