I have used the 81-030 Acorn Sliding glass door rollers for years. The original screw I have that fastens the roller to the door is too large to fit into the threads on the glass door roller.
What size/type of screw do I need?

Sorry to hear that you've having trouble, Steve. The 81-030 is compatible with our 33-097 self-tapping machine screw. This should be a suitable fastener for your door.
