How pounds is this anchor rated for?

Hi! Thanks for your question. Up to 55lb per single plug.

Will these work on thin paneling such as hollow doors or RV walls?

I’m not sure. They are pretty deep (over 1 inch) and not sure if they would compress enough to hold securely on thin panel. For that purpose I would use another style mollie that is made to compress with greater rear support.

Can these be used with # 6 screws?

Hello, thanks for the question. #6 screw would run small for the 5/16", we recommend #8-#12 for this plug size.
