Which fastener is used in areas of low temperature 250 Degrees or below?

Explanation:
In areas exposed to low temperatures, fastener material choice focuses on maintaining predictable strength and avoiding embrittlement. Metals can become more brittle and lose ductility when cooled, which raises the risk of cracking or fatigue under load. Non-metallic fasteners—such as certain polymers and reinforced composites—tend to maintain more stable mechanical properties and can offer electrical insulation and corrosion resistance in cold environments. For service at or below about 250 degrees Fahrenheit, non-metallic fasteners are preferred because they are less prone to the brittleness seen in some metals and still meet the needed strength and performance. Hence, non-metallic is the best fit for low-temperature areas.
