Product Description

The Metric Hex Bolts M12x50 are externally threaded fasteners designed according to DIN 933 M12 Bolts standards, featuring a 12 mm nominal diameter and 50 mm shank length. Constructed from high-strength steel or stainless steel (ISO 898-1/A2-70), these M12 External Hex Screws provide a tensile strength of 800 MPa minimum, with zinc-plated or hot-dip galvanized surface treatments for corrosion resistance. Designed for structural applications in machinery, automotive assemblies, and construction frameworks, they operate effectively in temperature ranges from -50°C to +250°C depending on coating. The hex head enables secure torque application with standard 19 mm wrench sizes, while full ISO metric thread engagement ensures reliable load distribution. Key advantages include standardized dimensions for interchangeability and vibration-resistant locking when paired with nylon inserts, though bulk installation requires proper torque calibration tools. Meets DIN 933/ISO 4017 tolerances for industrial fastener applications.
