McMaster-Carr's 75-pack square finishing plug is designed to fit 100mm diameter tubes and has a 6mm wide hole allowing it to be attached securely onto the tube for protection. Made from zinc, this plug provides robustness while remaining lightweight and easy to use. Its square shape fits conveniently into recessed panel holes, ensuring that the finish of your panel is seamless. Additionally, the plug's ability to fit panels between 5mm and 6.3mm thick ensures versatility in its applications, making it perfect for any panel with a closed off hole requiring finishing. The pack provides value for money as you purchase multiple plugs at once without needing individual ones each time, making this an ideal item for production lines or large projects where many finish plugs are required.
