Product Description

The M3x12 hex socket screws, also known as Cylindrical head Allen screws or Socket head cap screws M3x12, feature a precision-engineered cylindrical head design with a 6mm outer diameter and a 2.5mm hex socket drive. Made from high-grade steel or stainless steel (ISO 4762/DIN 912 standards), these screws deliver up to 1100 MPa tensile strength. Their M3x12 thread offers a 12mm nominal length (actual thread engagement ~10mm) and 0.5mm pitch. The screws typically operate in -50°C to +150°C environments, with optional zinc/nickel plating for corrosion resistance in industrial machinery, automotive assemblies, and electronics. Advantages include high torque transmission via the hex socket and flush mounting capability, though alignment sensitivity during installation requires proper tooling. The compact 5.5mm head height suits space-constrained applications.
