Product Description

This metric hex bolts M5x8 features an external hex head design (M5-8) compliant with DIN 931 standards, constructed from stainless steel A2-70 with a strength grade of 8.8. The M5x8 hex cap screws metric measure 5mm in diameter and 8mm in nominal length, designed for direct mechanical fastening of modules, plates, or structural components without requiring additional interfaces. With a corrosion-resistant finish, it operates effectively in -50°C to +150°C environments and supports industrial applications including automotive assembly, machinery manufacturing, and electronics enclosures. The external hexagon enables high torque transmission using standard 8mm wrenches, though repetitive disassembly may wear the head geometry. Critical specifications include a 13.2mm head width, 3.5mm head height, and 0.8mm thread pitch for reliable load distribution. Its advantages include high tensile strength and vibration resistance, while limitations involve potential galvanic corrosion in mixed-metal setups.
