Product Description

The M3x18 hex socket screws, also referred to as cylindrical head hex screws or Allen socket screws M3x18, are high-strength fasteners with a cylindrical head profile and internal hexagonal drive. Designed for precision assembly, these screws feature a threaded shank length of 18mm and M3 diameter, made from grade 8.8 steel with zinc plating for corrosion protection. The hex socket drive enables high torque transmission using standard Allen keys, suitable for applications in automotive engineering, industrial machinery, and electronics manufacturing. These screws operate effectively in temperature ranges from -50°C to 150°C, with a compact head design that reduces protrusion in tight spaces. Advantages include vibration resistance and reliable fastening strength, though they require proper tool alignment during installation. Compatible with DIN 912 standards, they are commonly used in equipment requiring flush surface finishes and secure mechanical joints.
