Beta INOX stainless steel tools are designed for use in critical environments where particles from corrosion are unacceptable, such as nuclear facilities, pharmaceutical production (Class C), biotech, food production, and offshore marine environments. The use of mild steel tools in these environments can lead to corrosion and rust formation, even on stainless steel fasteners. Beta INOX tools are constructed of magnetic stainless steel (AISI 420), expertly heat-treated to achieve industrial grade strength.
