Product Description

The M8x20 hex flange screws, also known as hexagonal flange bolts M8x20, are precision-engineered fasteners designed for robust industrial applications. These screws feature an integrated hexagonal head with a flanged base, eliminating the need for separate washers. The M8x20 specification indicates an 8mm nominal diameter and 20mm shank length, suitable for medium-duty connections in machinery, automotive assemblies, and structural frameworks. Manufactured from high-grade steel (typically ISO 898-1 Class 8.8 or equivalent), they offer tensile strength up to 800 MPa and a recommended tightening torque of 22-30 Nm. The flanged design enhances load distribution and vibration resistance, making them ideal for applications in manufacturing plants, renewable energy systems, and construction equipment. Key advantages include corrosion-resistant coatings (zinc-plated or hot-dip galvanized options), while limitations include non-adjustable grip length and potential galvanic corrosion in harsh environments. Operating temperature ranges from -50°C to +150°C depending on coating. Compatible with standard M8 nuts and tools requiring a 13mm hexagonal wrench.
