B8 class fasteners are manufactured from 304 grade stainless steel. They are durable fasteners for environments requiring high temperature and corrosion resistance.
It is widely used in the petrochemical, energy, food, pharmaceutical, water treatment, and maritime industries.
B8 fasteners are made from AISI 304 grade stainless steel, while B8M fasteners are made from AISI 316 grade stainless steel. B8M offers higher corrosion resistance and is preferred in aggressive environments.
