Product Description

The M4.2x45-2# screws are precision-engineered ISO 2# metric fasteners designed for heavy-duty industrial applications such as machinery assembly, automotive frameworks, and construction structures. These M4.2x45mm machine bolts feature a 4.2mm diameter and 45mm length with a 2# thread pitch, compliant with ISO standards for dimensional accuracy and mechanical strength. Constructed from high-grade steel with corrosion-resistant coatings, they operate reliably within a temperature range of -50°C to 150°C and withstand tensile loads up to 8.8 grade specifications. Their hexagonal head design ensures secure torque application, while the standardized threading guarantees compatibility with pre-tapped components. Key advantages include durability, vibration resistance, and ease of installation with standard tools, though specialized alignment may be required for high-stress environments. These fasteners are ideal for critical joints in aerospace, manufacturing, and infrastructure projects demanding stringent precision.
