What is the tensile strength of an SAE grade 6 bolt?

The tensile strength of an SAE grade 6 bolt is not specifically defined in established standards. SAE (Society of Automotive Engineers) grades are typically associated with specifications that describe properties such as tensile strength, yield strength, and hardness for steel bolts. However, SAE grade 6 is not a commonly recognized grade within the SAE classification system, as the most recognized grades include 2, 5, and 8, each with clearly defined tensile strengths.

Recognizing this absence of specification indicates that grade 6 does not adhere to the established tensile strength parameters that exist for other defined grades. Therefore, there is no tensile strength value defined for a grade 6 bolt, making this the most accurate choice among the provided options.
