ASTM A307 SIZES & SPECIFICATIONS
The ASTM A307 specification covers carbon steel bolts, rods/studs and anchor bolts ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. They have a low hardness and tensile requirements and are generally used in low-pressure, standard or normal temperature applications There are three grades A, B, and C* which denote tensile strength, configuration, and application.
You will often hear about A307 and Grade 2 bolts as being equivalent. While they are small differences they each are referred to as “low carbon” fasteners. A307 is an ASTM (industrial) spec, while Grade 2 is an SAE J429 Grade 2 (automotive) spec. A325TC Flat Bolt with Nut Washer
