Product Description

The M5x20 hex bolts are precision-engineered Metric M5 external hex bolts designed for robust mechanical fastening in industrial applications. Featuring an M5 hex head bolts design with a 10 mm across flats and 20 mm shaft length, these bolts offer a 1.0 mm thread pitch for seamless compatibility with standard M5 nuts. Constructed from high-grade steel with optional corrosion-resistant coatings, they operate reliably within temperatures of -30°C to +120°C and withstand vibration-prone environments. Ideal for machinery, automotive, and structural assemblies, their hexagonal head ensures secure tool engagement for precise torque application up to 8.8 strength rating. Key advantages include dimensional accuracy, durability, and broad industry compliance (ISO 4014/DIN 933), though limited in ultra-high-load scenarios due to compact sizing. The fully threaded design accommodates variable material thicknesses.
