## Questions & Answers

**Q: does counter sunk  section go on outside.  Does it matter?**
A: The countersink is for the screwhead to fit in so it finishes flush with the washer. Yes it does matter that you fix these the correct way; if they are fitted incorrectly the screw will be proud of the board you are installing. If this is a tile board then you won't be able to seal the boarded properly nor will you have a flat surface to tile on.

**Q: It says to seal surface so the wet plaster doesn't cause the disc to rust. What is suggested to seal ?**
A: Some tiles need to be sealed once installed, if water can't be absorbed through then the washer and screw will not rust.
Tile sealers are sold in many places.

**Q: What size and type of screw is needed and do you supply?**
A: The screw I am using are going through the center hole, which is 6.8mm, so buy something bigger

They are zinc coated, not stainless steel. Washers are rigid enough, not like other flimsy ones. So, they do the job.
