Hoping this didn't fall off a car! Found on the driveway, some kind of metal connector. There's a pinhole opening on the flathead top and the bottom is open. The number "25032" is stamped on the side of the middle. Approximately 1 inch long and 1/4 inch diameter. No threading. Could not find anything similar using Google image search, nor was the printed number giving me any results. Thanks for your help!
