replacing casement hinges on Pella window

A quick learner from Ohio says:
We have large Pella casement windows. First the screw holding the hinges started coming loose. Now the hinge itself came off the track. These windows still would be ok if we could open and close them efficiently. Do you need different sizes of hinges? How can we fix the screw popping out? What kind of lubicant should we use on the hinge track? Thanks, Julie

Julie, I don't believe you can change to a different hinge.

Pella parts only use Pella parts. I recommend re-using the hinge and moving up to a larger screw-- maybe longer (make sure not to screw into the sash, as you may damage the glass).

Now, if screw length isn't a solution, you could try using a thicker screw.

We recommend using a silicone-based lubricant spray on your hinge track, as some oil-based lubricants tend to collect dirt.
