What's the material

1. Stainless steel: commonly used for applications that require corrosion resistance and high strength.

2. Carbon steel: a commonly used material for general purpose bolts that offer good strength and durability.

3. Titanium: used in high-performance or specialized applications due to its high strength-to-weight ratio and corrosion resistance.

4. Brass: commonly used for decorative purposes due to its bright golden color, but also offers good corrosion resistance.

5. Aluminum: used for lightweight applications where weight is a concern, but not ideal for high load applications due to its relative softness compared to other materials.

6. Alloy steel: used for high-stress applications, where the strength and durability of the bolt are critical.
