Grade

Description

Grade A

Bolts, studs, and threaded rod having a minimum tensile strength of 60 ksi and intended for general applications,

Grade B

Bolts, studs, and threaded strength of 60 to 100 ksi and intended for flanged joints in piping systems with cast iron flanges, and

Grade C

Replaced by Specification F1554 Gr.36

(A) Threaded rod is not usually produced to Grade B, but can be when specified by the purchaser.
