## Questions & Answers

**Q: Will these screws rust if used externally to fix battens?**
A: We ll I would say maybe coz they was designed for indoor use only. But if its all the way home then only the face might rust.

**Q: brick wall with raw plugs?**
A: Yes.  ? are we asking about the original RAWL plug if so it was--is a good fixing, providing your hole  is deep enough to take the screws length, push the plug in to the depth of the hole and push  it in so that it has gone 1/4 of an inch further in. this will make a good grip for the holding screw, plastic or wood plugs finest thing since sliced bread. I hope this helps. Regards Big D.

**Q: I am hanging part of a wood pallet on my brick wall. Will I need raw plugs?**
A: Yes 
Red plugs should do 
Screw size allow for thickness of wood and depth of plug
Masonry drill should be same diameter as plug
Easier if you can locate holes in the masonry

**Q: Are these suitable to hang a tv on a plasterboard wall going through the metal studs?**
A: Don't know , hanging TV on metal studs i would use captive insert system
