Screw May Need Replacement

I?m trying to repair an awning-style operator on my jalousie windows. The crank (pictured) keeps unscrewing from the operator when I try to close the windows, which makes me think I need to replace the screw itself, within the handle. If this is the case, can someone recommend the proper replacement part? Any other advice would be greatly appreciated!

Hello! When the worm gear comes out of the operator like this, that means that the whole mechanism is stripped out. It can't be repaired or replaced, so you'll need an all new operator.

Now, I wasn't able to find an exact match, but our 39-252 is similar. Look over our dimensions and let me know how well they match up. Take particular note of the threaded hole in the link arm, which is 5/16" in diameter. Also see the 39-251 for the opposite side.

Please let me know your thoughts.

Thanks for the response! Unfortunately the dimensions don't quite match, but I may have found another solution in any case. I'll reach out again if that doesn't work.
