Product Description

The Cylindrical head hex screws (M12x50 socket screws) are precision-engineered DIN 912 M12 bolts designed for robust fastening in heavy-duty industrial applications. Featuring a 12mm diameter and 50mm shank length, these socket head cap screws accommodate standard M12 hex keys, ensuring secure torque transmission up to 125 Nm. Constructed from grade 12.9 alloy steel with optional zinc-plated or stainless steel finishes, they operate reliably in temperatures from -50°C to +150°C. Commonly used in machinery assembly, automotive frameworks, and structural engineering, these M12x50 socket screws offer high tensile strength (1200 MPa) and vibration resistance. Their cylindrical head design enables flush mounting in confined spaces, though installation requires proper countersinking. Limitations include compatibility only with M12-rated components and specialized tool requirements for optimal torque application.
