I'm guessing these are what are called "well nuts". A flanged rubber tube with a brass threaded insert in one end. I had some that the threaded part turned in the rubber. I carefully used a little super glue on the metal part and quickly reinserted in the rubber. Worked good. Try to keep it straight, and check the threads on the screws. Or get new well nuts at a hardware store or bike shop.
