Both the rivet body and mandrel are made of stainless steel, providing a stable structure suitable for long-term fastening. The large flange round head increases the contact area with the material surface, helping to improve connection stability. The blind rivet design allows for single-sided installation, suitable for installation environments where the back side is inaccessible. The round head has a flat appearance, resulting in a clean finish after installation, ideal for applications where aesthetics are important.
