I recently received a a Gillette SS TTO. The screw is that 4 pronged thing that you need to get out. So I took a screwdriver and notched it and made it work.. Now the original screw is fine, but I was wondering if anyone had the size of it.
That screw has left handed threads, your not going to find a replacement at Home Depot.
Also it's smaller then a #10-24 more likely #6-32 LH or even #4-40.
