Product Description

The M3x28 hex socket cap screw, compliant with DIN 912 M3x28 screw standards, is a cylindrical head metric socket head screw designed for precision fastening. This M3x28 metric socket head screw features a 3mm nominal diameter, 28mm length, and ISO 4762-compliant internal hexagon socket. It is manufactured from high-tensile steel (grade 12.9) with optional zinc plating or 304 stainless steel variants for corrosion resistance. Typical applications include machinery assembly, automotive components, and electronics enclosures. The low-profile cylindrical head provides space-saving installation in tight clearances. Advantages include exceptional shear strength (up to 900 MPa) and vibration resistance, though installation requires specific hex keys (2.5mm) and extended lengths may require pilot holes. Operating temperature ranges from -50°C to 120°C for steel variants. Its standardized dimensions ensure compatibility with DIN 912-certified tools and fixtures across industrial equipment sectors.
