How do the boat folks do it?
Boats will use stainless.

Replacing Schwintek mount screws with shoulder screws and z-clips

Like others, I have a Schwintek bedroom slide. The installation has a lot of sheared screws and I suspect other screws that appear fine are actually sheared 1/2" or more down the length of each screw.

I noticed the distance between the slide out front motor and slide out wall are too close and is causing some physical wear on the slide out wall around the motor locations (my first clue somethings not right).

While investigating the slide out wear, I wanted to ensure the slide out wasn't 'racking' and decided to ensure slide out motor synchronization. While ensuring motor sync, I noticed the frame mounted to the coach wall is flexing (yet not bending) back and forth, pulling the motor assembly away from its mount on the coach wall (and causing the motor to pull into the path of the slide out), then returning in place after movement has stopped. It will surely bend permanently if I don't resolve this now.

So...has anyone seen this behavior before. Based on some earlier comments in this forum I will be replacing ALL Schwintek mounting screws with stainless steel shoulder bolts and Z-clips.

I'd like to simply drill new mounting holes and replace the screws, but I've lost any trust the coach frame will endure the long term stress and will simply work it's way out).

Has anyone noticed similar movement on their Schwintek frames? Comments and recommendations are appreciated.
