Product Description

The M8x50 external hex bolts, designed as metric external hexagonal bolts, are precision-engineered fasteners with an 8mm nominal diameter and 50mm shank length. These M8*50 hex head bolts feature a standard hexagon head for tool compatibility (e.g., 13mm wrench size) and thread pitch of 1.25mm. Manufactured from high-grade steel (ISO 4014/4017 standards), they offer tensile strength up to 800 MPa, suitable for industrial machinery, automotive assemblies, and structural applications requiring vibration resistance. Optimal performance is maintained within -30°C to +120°C temperature range. Key advantages include corrosion-resistant coatings (zinc-plated or stainless variants), precise dimensional tolerance (±0.1mm), and 90 N·m maximum torque capacity. Installation requires standard metric hardware tools without specialized interfaces or power requirements. Potential limitations include reduced grip length in constrained spaces due to full thread design.
