In general, since the minimum strength requirement of a Grade 2 is greater than that of an A307A, a Grade 2 can be successfully utilized in applications where an A307A is specified, as approved by the “Engineer of Record”. The SAE marking standard starts with grade 2, indicated by a bolt head with no markings whatsoever. A grade 2 bolt made of low-carbon steel has a tensile strength of 64,000 pounds per square inch or less. Tensile strength is the amount of pull the bolt can withstand before breaking. 14.09.2020 · Bolt Depot - Standard U.S. Hex Bolt Sizes and Thread Pitches.pdf. Bolt Grade Markings and Strength Chart.
