Product Description

The M5x55 socket cap screw is a precision-engineered cylindrical head hexagon socket screw designed for robust mechanical fastening applications. With a thread size of M5 and length of 55mm, this Hex socket screw M5x55 features a cylindrical head profile that enables low-profile installation while providing superior clamping force. Manufactured from grade 12.9 alloy steel, it offers 1,220 MPa tensile strength and works within temperature ranges of -50°C to +150°C. The Cylindrical head M5x55 screw is particularly suitable for industrial machinery, automotive assemblies, and electronic enclosures where space constraints exist. Its internal hex drive (4mm key size) ensures secure torque transmission up to 9.5 Nm while preventing tampering. Primary advantages include vibration resistance and corrosion protection through optional zinc-nickel plating. The 12mm head diameter and 8mm head height maintain optimal strength-to-size ratio, though requiring dedicated hex key tools for installation. This fastener is widely applied in precision equipment manufacturing and heavy-duty structural connections.
