Product Description

The M5.5*18-2# screws are precision-engineered M5.5 thread fasteners with an 18mm length, designed for high-load applications in construction, machinery, and automotive industries. These 2# series bolts M5.5 feature a corrosion-resistant zinc-plated finish and comply with ISO 4017 standards, offering tensile strength up to 800 MPa. Compatible with standard M5.5 nuts and washers, they operate reliably in temperatures from -30°C to 120°C. The hexagonal head design ensures secure torque transmission using 8mm wrenches. Key advantages include vibration resistance and environmental durability, though prolonged exposure to acidic conditions may affect surface integrity. Each unit undergoes rigorous QA testing for dimensional accuracy (±0.1mm tolerance) and thread alignment. Ideal for structural assemblies requiring M5.5-sized fasteners with 18mm grip length.
