FAQ
Q1: What is the benefit of "All Steel" construction in a blind rivet?
A: "All Steel" means both the body and the mandrel are made of 304 Stainless Steel. This provides uniform corrosion resistance across the entire fastener and prevents the galvanic corrosion that can occur when two dissimilar metals (like aluminum and steel) are in contact in a corrosive environment.
Q2: What does GB12618.4 standard mean?
A: GB12618.4 is the Chinese national standard for open-mouth, core-pulling all-steel rivets, ensuring strict quality, tensile strength, and dimensional consistency.
Q3: Why is "White washing" mentioned for the surface treatment?
A: White washing (a term often used for a light oil or zinc coating on the mandrel) is applied to the core to ensure it pulls smoothly and breaks consistently during installation. This treatment protects the core during processing and storage.
Q4: What is the advantage of a dome head?
A: Dome heads offer a low-profile, smooth finish that enhances the appearance of assemblies while maintaining strength.
