Product Description

The 316 Stainless Steel M20 Bolts and Fasteners are precision-engineered components designed for high-performance industrial applications. These 316 SS M20 Fasteners feature a 20mm thread diameter and are compatible with M20 316 Stainless Nuts, ensuring secure connections in corrosive environments. With a tensile strength of 515 MPa minimum and a working temperature range of -50°C to 450°C, they maintain integrity under extreme conditions. The system supports direct integration with standard industrial modules through ISO 4014/4017 specifications, requiring no additional adapters. Typical torque values range from 210-310 Nm depending on lubrication. Widely used in marine, chemical processing, and food-grade installations, these fasteners offer superior chloride resistance compared to 304-grade steel. Their polished surface finish (Ra ≤0.8μm) prevents bacterial growth while the hexagonal head design enables 180° tool access. Primary limitations include higher material costs versus carbon steel variants and reduced magnetic permeability. The corrosion-resistant properties make them ideal for coastal installations and chemical exposure scenarios where standard fasteners would degrade.
