Product Description

This metric M5 hex bolts 40mm is a precision-engineered external hex head bolt M5x40, designed for robust fastening in machinery, automotive, and construction applications. Manufactured from high-grade steel with a zinc-plated or stainless-steel finish, it features a 5mm thread diameter, 40mm length, and a hexagonal head for tool compatibility. Rated for tensile loads up to 800 N and torque values of 4.6 Nm (grade 8.8), it operates reliably in temperatures ranging from -50°C to +120°C. The M5-40 hexagonal screw metric excels in corrosion resistance and vibration resistance but requires precise torque calibration to avoid over-tightening. Ideal for securing panels, brackets, or structural components in industrial settings, its standardized dimensions ensure compatibility with M5 nuts and threaded inserts.
