The Corrosion Resistant Countersunk Head Riveted Nuts are made of metal. You can apply a coating to them to prevent corrosion - but our main transportation packaging also has a waterproof feature. The pallets used to hold these nuts are completely wrapped in thick waterproof polyethylene stretch film.
During the entire process of sea or air transportation, this protective layer can actively isolate the goods from possible rain, humidity and accidental moisture, preventing such factors from causing damage to the goods. As a result, these nuts will not be damaged by oxidation or moisture absorption before they reach your warehouse.
We ensure the quality of each batch of Corrosion Resistant Countersunk Head Riveted Nuts through a strict quality control system. This process begins with the use of certified raw materials, and then during the production process, we conduct inspections - such as in stamping, turning, and coating.
We attach great importance to the above core parameters and use SPC technology to monitor them in real time to build a solid quality defense line. This rigorous supervision mechanism ensures that every nut fully meets the preset mechanical performance and appearance aesthetic standards before entering the final inspection stage.
We make sure our Corrosion Resistant Countersunk Head Riveted Nuts are top quality, thanks to a strict quality management system—one that’s certified to international standards like ISO 9001.
When we’re making them, we do thorough checks as we go, plus a final inspection to check things like dimensions, thread quality, and what the material’s made of. We also test each batch for mechanical properties. This focus on quality control means every one of these nuts you get will work consistently and reliably.
