What material is A307?
The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C* which denote tensile strength, configuration, and application.
Is A307 a Grade 5?
A307 is basically an ungraded bolt and A325 is grade 5 or so.
What grade is a A307 bolt?
ASTM A307 Grade A is a standard material specification for medium strength carbon steel fasteners specially bolts, studs and threaded rods for general purpose applications. Grade A is a heat treated carbon steel bolting material with minimum tensile requirement of 60 ksi and hardness range from 121 to 241 BHN.
Is A307 stainless steel?
ASTM A307 Carbon steel bolts and studs, 60,000 psi tensile strength. ASTM A320 Alloy steel and stainless steel bolting materials for low temperature service. Replaced by ASTM F3125. ASTM F593 Stainless steel bolts, hex cap screws, and studs.
What is astastm A307 grade B?
ASTM A307 Grade B is a standard material specification for medium strength carbon steel fasteners specially bolts, studs and threaded rods for general purpose applications.
What is an A307 bolt?
Yes, I meant A307 bolts, sorry about that! Nonheaded anchor bolts, either bent or straight, having properties conforming to Specification A 36 (tensile strength of 58 to 80 ksi (400 to 550 MPa)) and intended for structural anchorage purposes.

What are the A307 requirements for machine screws?
A307 specification does not cover the requirements for machine screws, thread cutting/forming screws, mechanical expansion anchors, or other similar externally threaded fasteners. When tested, sampled specimens shall adhere to specified values for chemical composition, hardness, tensile strength, yield point, elongation, and dimensions.
