Astm A307 Specification Verified Today

The specification originally defined three distinct grades—A, B, and C—based on their mechanical properties and intended end-use.

The is the industry standard for carbon steel bolts, studs, and threaded rods with a minimum tensile strength of 60,000 psi. It covers diameters ranging from 1/4" to 4" and is a "workhorse" specification for general construction and non-critical structural applications. Grades of ASTM A307 astm a307 specification

: Designed for general-purpose applications. These are common "low-carbon" bolts used in wood-to-wood or wood-to-steel connections. They have a minimum tensile strength of 60 ksi but no specified maximum. These are common "low-carbon" bolts used in wood-to-wood

: Originally used for unheaded anchor bolts (bent or straight) for structural anchorage. This grade was officially withdrawn in 2007 and replaced by the ASTM F1554 Grade 36 specification . Mechanical & Chemical Requirements

No configuration limits; can be headed bolts, bent bolts, or threaded rods.
