Hello! I recently had my rollers recovered for the first time, and am having trouble screwing in the retaining screws in the shaft. The screws worked fine previously. Any thoughts?

The tap and t-head worked like a charm. I found both locally at a hardware store. Thanks again!
Correction: the diameter is 1/4″ but the thread pitch is still 28.

A local machine shop could clean it for you. Be sure to tell them that the rubber should not rest on a flat surface.
Another idea is to use a round wire brush. The bristles should be a brass or nylon, because steel may damage the interior threads. A Dremmel attachment might work. But proceed with caution.
I found one that is 5/16 with a 24 pitch at an automotive store (A-Line). Do you think this is a special-order size, or can you suggest what stores might carry this size? I’ll keep looking online.
It’s best to bring in the screw to be sure, but I just measured one: 3/16″ diameter with a thread pitch of 28 (meaning 28 threads per inch).
Is there a certain size I should look for in an automotive or hardware store, or bring the screw in for someone to assist me with this?
Likely there is roller material in the threads. You may need to use a tap to clean out the threads.
