  • A307B Bolts

A307B Bolts

Application: A307B Bolts are commonly used for flange joints in piping systems with cast iron flanges. A307B Bolts have a tensile strength range of 60-100 KSI. These are very similar to A307 Grade A, only the head dimensions are different; A307A uses a standard Hex head where as the A307B Bolts use a Heavy hex [...]

Bored Bolts

The SB of bored bolts refers to the ultimate tensile strength of bolts, indicating the maximum resistance of bored bolts to failure under tension. Tensile strength is the maximum nominal tensile stress of the specimen before breaking. It is the critical value of metal transition from uniform plastic deformation to locally concentrated plastic deformation, and [...]
