Used when a flush mounting, high strength screw is required. Commonly used in tools and dies where moving parts pass over the fastened area.

• High alloy metric socket cap screws are comparable, but not exactly equivalent to U.S. alloy steel socket cap screws. Ideal for precision assembly work with close tolerances and applications needing a well-tooled appearance. Supplies greater tensile strength than equivalent sizes of Class 8.8 or 10.9 hex head cap screws while requiring less surface area or conterbore since the fastener is internally wrenched
• High alloy metric socket cap screws shall be made from an alloy steel which conforms to the following chemical composition requirements-- Carbon: 0.20-0.50%; Phosphorous: 0.035% maximum; Sulfur: 0.035% maximum; and one or more of chromium, nickel, molybde
