Product Description

The M5x50 hex socket cap screw is a cylindrical head metric socket head screw designed according to DIN7991 standards. Featuring an M5 thread diameter and 50 mm length, this fully threaded fastener is crafted from high-tensile steel with a corrosion-resistant zinc-plated finish. The cylindrical head design with an internal hex socket (6 mm key size) ensures secure installation using standard hex keys. Operating effectively across industrial temperature ranges (-30°C to +120°C), it delivers reliable clamping force in machinery assembly, automotive engineering, and electrical equipment applications. The DIN7991-compliant geometry provides excellent shear resistance and vibration tolerance, while the compact head profile enables use in space-constrained environments. Key advantages include standardized compatibility, high mechanical strength, and chemical-resistant surface treatment, though requires proper torque control during installation to prevent head stripping. Ideal for permanent structural fastening in heavy-duty mechanical systems.
