What are the parts of a hi-shear rivet?

The parts of a hi-shear rivet consist of a cadmium-plated steel alloy stud and an anodized aluminum collar. The steel alloy stud is used for its high strength and resistance to shear forces, which is crucial in applications where structural integrity is paramount, such as in aircraft construction. The cadmium plating provides corrosion resistance, which is essential in aviation environments where exposure to moisture and other corrosive elements can occur.

The anodized aluminum collar complements the steel stud, offering a lightweight yet strong fastening solution. Anodizing enhances the aluminum's surface properties, improving corrosion resistance and wear characteristics. This combination of materials ensures that the hi-shear rivet can withstand the demanding conditions typical in aviation applications while maintaining a secure and reliable joint.

This answer demonstrates an understanding of the materials and their properties, which are critical in aviation structural applications. The other options do not provide the correct combination of materials typically used in hi-shear rivets, emphasizing the significance of material selection in structural integrity and performance in aviation environments.
