The 4.0mm diameter and 25mm length provide optimal grip range for thin to medium-gauge materials. Open-end design allows for efficient installation with standard rivet tools. Aluminium construction resists oxidation in demanding environments while maintaining excellent strength-to-weight ratio. Ideal for automotive, aerospace, and general fabrication work where durability and precision matter.
