Product Description

The Cylindrical head hex socket screw M4x75 (also referred to as M4-75 hexagon socket cap screw or Cylinder head hex drive screw M4) is a metric fastener designed for precision applications. It features a cylindrical head with a hex socket drive (ISO 4762/DIN 7984 standard), M4 thread diameter, 75mm shaft length, and a pitch of 0.7mm. Typically manufactured in steel grade 8.8 or stainless steel A2/A4, it offers tensile strength up to 800 MPa and corrosion resistance for industrial environments. Suitable for machinery assembly, automotive components, and electronics enclosures, it operates within -30°C to 120°C and withstands moderate vibration. Installation requires a 3mm hex key with recommended torque of 2.5-3.0 Nm. Advantages include compact head profile, high load capacity, and secure torque transfer, while limitations include potential socket wear under excessive force and specialized tool dependency. Surface treatments like zinc plating or black oxide enhance durability.
