## Questions & Answers

**Q: How pounds is this anchor rated for?**
A: Hi! Thanks for your question. Up to 55lb per single plug.

**Q: Will these work on thin paneling such as hollow doors or RV walls?**
A: 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.

**Q: Are the screws stainless or zinc coated?**
A: Stainless steel

**Q: Can these be used with # 6 screws?**
A: Hello, thanks for the question. 
#6 screw would run small for the 5/16", we recommend #8-#12 for this plug size.
