Product Description

The metric hex bolts M3x18 (also known as hex cap screw M3-18 or M3-18 external hex bolt) are ISO 4014/DIN 931-compliant fasteners with a 5.5mm hex head and M3 thread diameter, offering an 18mm shank length. Constructed from grade 8.8 carbon steel or A2/A4 stainless steel, these bolts feature zinc-plated or galvanized coatings for corrosion resistance, suitable for temperatures ranging from -30°C to 120°C. Designed for industrial applications including machinery assembly, automotive frameworks, and electronic enclosures, they provide high tensile strength (800 MPa) and shear resistance. The external hex design enables tool engagement with standard 5.5mm wrenches or sockets. While offering secure fastening in high-vibration environments, they require precise torque control during installation. Typical usage spans manufacturing, construction, and renewable energy sectors where standardized metric hardware is preferred.
