Screw no longer holds in spiral rod

Question

Hello,

My townhouse has Patriot windows. Most of these windows have developed an issue in the same place. The screw on the photo doesn't hold and the rod (?name) doesn't stay in. I think they were probably over tightened when assembled. Also, the lubrication wasn't good enough and this contributed to the eventual damage. How could I fix this?

I look forward to hearing from you.

Thanks!

Julian

Thanks for posting. For this kind of Patriot window, they often use our Series 600 spiral tilt window balances with either our 15-046 or 15-047 pivot shoe. Each has a different thickness, however, so keep that in mind. As for the screw, that's just a safety feature to the helps keep the spiral from slipping out. While yours is probably over-tightened, it shouldn't interfere with performance of window. Check out the video below to see how a balance can perform without the screw.
