It depends on how the steel is heat treated, so there isn't a single answer.
SAE grade of a bolt refers to the classification system established by the Society of Automotive Engineers (SAE) that indicates the strength and material properties of the bolt. The grades range from 1 to 8, with higher numbers indicating stronger bolts, typically made from alloy steel with specific heat treatment processes. Each grade has a specified minimum tensile strength, which helps in determining the appropriate bolt for various applications. Common grades include Grade 2, Grade 5, and Grade 8, with Grade 8 being the strongest.

The SAE equivalent of ASTM A572 is typically designated as SAE J2340. ASTM A572 is a high-strength, low-alloy structural steel used in various construction applications, while SAE J2340 refers to a similar type of high-strength steel, often used in automotive and structural applications, emphasizing good weldability and formability. Both specifications serve similar purposes but may have different chemical compositions and mechanical properties tailored to their respective applications.

10.9 on a metric bolt indicates the hardness (or load, tensile strength, and hardness) of the bolt. This is almost as high as they get and is about the equivalent to a grade 8 SAE or USS bolt. 8.8 is also a common metric hardness.

It will depend on the Alloy. You need the alloy steel AISI - SAE material designation; such as 4140 or 8620. Mechanical engineering handbooks will have the mechanical properties listed in an appendix; such as UTS, YS, Modulus (E), etc. In addition, steel distributor's will have books (free) that have the mechanical properties listed. I did attempt to add a website as an example of where you could go on-line as well. I am not sure where or how the link will appear.

An SAE bolt is a type of bolt that adheres to the Society of Automotive Engineers (SAE) standards, which specify dimensions, materials, and mechanical properties for fasteners used in automotive and engineering applications. SAE bolts are typically measured in inches and are commonly used in the United States. They come in various grades, reflecting their strength and suitability for different applications. These bolts often feature a hexagonal head and are designed to be used with standard SAE tools.

Strut bolts are typically made from high-strength steel and can vary in grade depending on the manufacturer and specific application. Common grades for strut bolts include Grade 8 (as per the SAE standard) or equivalent metric grades like 10.9 or 12.9. The grade indicates the tensile strength and hardness of the bolt, which is crucial for ensuring safety and durability in suspension systems. Always refer to the vehicle's specifications for the appropriate grade when replacing strut bolts.
Bolts are typically classified into several grades based on their strength and material properties. Common grading systems include the American Society for Testing and Materials (ASTM) grades, such as ASTM A307, A325, and A490, as well as the SAE grades, like Grade 2, Grade 5, and Grade 8. Additionally, metric bolts are graded according to ISO standards, such as 8.8, 10.9, and 12.9. Each grade indicates the bolt's tensile strength and suitability for different applications.
