Hello, my name is John with KOHLER Customer Service. I am happy to assist you with your toilet paper holder question. The part number for the screw for the 490-CP Memoirs Wall-Mount Single Post Toilet Paper is part number 88490. I’m sorry, but since the bonnet is all one part of the toilet paper holder, the bonnet is not available as a service part. For additional assistance on this inquiry, please contact our Customer Care Center at 1-800-4KOHLER. (1-800-456-4537) Thank you for your inquiry and choosing the Bold Look of KOHLER.
Thank you for your inquiry. Please reference the More Info. tab towards the bottom of the Home Depot's product page for this Memoirs Toilet Paper Holder (to the right of the Description tab). It has the installation instructions you can open, and pages 8 and 9 will show you how the unit is attached to the wall. It sounds like you will have to loosen the 8-32 setscrew with a hex wrench underneath the "bonnet" that fits against the wall (there will be a small hole underneath so you can get at the setscrew). Then you can remove the tissue holder ring from this bonnet and you will see a screw on the end of the bonnet. Try tightening this screw.
