Product Description

The M12x65 hex socket screw is a Cylindrical head cap screw designed for high-torque applications in industrial machinery, automotive assemblies, and heavy equipment. Featuring a cylindrical head with a hexagonal socket (ISO 4762/DIN 912 standard), this Socket head screw M12x65 has a full thread length of 65mm and M12 diameter. It typically utilizes Allen key drive (hex key size 10mm) for installation. Manufactured from Grade 12.9 alloy steel or A4-80 stainless steel variants, it offers tensile strength up to 1,220 MPa. The screw operates effectively in temperatures ranging from -50°C to +250°C, with optional zinc-plated or black oxide coatings for corrosion resistance. Its low-profile head design enables use in confined spaces, though installation requires precise alignment due to limited wrench access. Common applications include structural frame assembly, hydraulic systems, and precision tooling fixtures where vibration resistance and secure fastening are critical.
