Which list contains physical properties for fasteners?

The provided answer includes thermal expansion, corrosion resistance, and density, which are all significant physical properties relevant to fasteners.

Thermal expansion refers to the tendency of materials to expand when heated and contract when cooled. This property is crucial in applications where fasteners are subjected to varying temperatures, as it can affect the integrity of the joint.

Corrosion resistance indicates a material's ability to withstand degradation due to environmental factors, which is vital for fasteners exposed to moisture, chemicals, or other corrosive conditions. Selecting fasteners with good corrosion resistance ensures longevity and reliability.

Density measures the mass per unit volume of a material and is important when considering the weight of a fastener in applications where mass affects performance.

The other options contain properties that, while important, do not cover the same breadth of physical properties as the chosen answer. For example, choices containing yield strength, elasticity, and tensile strength focus more on the material's strength characteristics under stress rather than broader physical attributes like thermal behavior and corrosion-related performance.
