ASME SA307 Threaded Rod & Anchor Bolt manufacturer in India, see astm a307 bolt dimensions and shear strength
ASTM A307 Bolts are specified to have carbon steel and in the range of ¼ inches to 4 inches of diameter. There are three major grades as A, B and C in this specification often made from the A36 round bars. Viha Steel & Forging is a leading manufacturer and supplier of the different types of the Astm A307 Threaded Rod in the different types. The different types are specified with tensile strength, configuration and the different application types. The mechanical properties vary for the different application requirements.
The Astm A307 Grade A Bolts is headed bolt, threaded rod and bent bolt type for general purpose applications. The grade B is heavy hex bolts and studs for flanged joints. The astm a307 hex bolt can be used with tools and applied high torque force to tighten it in place. The type C bolts are non-headed anchor bolts. These can be bent or straight and are intended for structural usages. The A307 Anchor Bolt is painted green for identification. This part will project out from the concrete structure. Depending on the customer requirements, some of the anchor bolts are marked permanently.
The A307 Thru Bolt and others in the grade A come with 60ksi minimum tensile strength while grade B can range from 60 to 100ksi and grade C from 58 to 80ksi minimum tensile strength values. The astm a307 stud bolt is used with applications where the stud is needed. The material has carbon, manganese, phosphorus and sulfur in the composition.
