I was dissatisfied with the second fitting I installed. For a reason I couldn’t understand, the stud end of the fitting wouldn’t accept as many threads as the eye fitting had. Here are photos to illustrate:
I took the fitting apart and reformed the uneven threads around the cone. Reassembly was not really any better. I took it apart again and looked into the other end. There is a “former” that inserts into the female side of the fitting. That former was skewed to one side, which prevented the end of the cone-shaped wire side to seat evenly and snugly. After a few more minutes of prying the former around with a tiny screw driver, I captured the stud into the vice (with wood blocks to keep from damaging the stud threads), and gently tapped the high side of the former with a mallet/screw driver. It unjammed immediately, and I was able to seat symmetrically into the bottom of the female side. Here’s a photo of the former from StaLoc’s website:
This shape fits perfectly into the bottom of the female-threaded side of the fitting, and “forms” the wire around the end of the cone insert. Once I had the former seated, the fitting went together perfectly.
