CORROSION RESISTANT - The Beta 96BP INOX ball-end allen hex key wrenches are manufactured with stainless steel, making them highly resistant to corrosion and rust and highly durable in tougher environments with high humidity and moisture. DURABILITY - Stainless steel is a tough and durable material, capable of withstanding heavy use and impact. Beta INOX tools are constructed of magnetic stainless steel (AISI 420), expertly heat-treated to achieve industrial grade strength. APPLICATIONS - 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. BALL-END - The ball end of the hex key allows for work at angle of up to 30° to screw axis, great for access in hard-to-reach areas. SPECIFICATIONS - This 3mm metric hex key measures 101mm (3.98") on the long side and 24mm (.94") on the short side.
