Metric Class 8.8 Hex Flange Bolt, Non Serrated, DIN 6921, Plain
Our Metric Class 8.8 Hex Flange Bolts manufactured to DIN 6921 with a non‑serrated flange and plain finish are designed for reliable, high‑strength fastening in industrial, mechanical, and general‑purpose applications. Produced from medium‑carbon steel and heat‑treated to Class 8.8 specifications, these bolts provide a balanced combination of tensile strength, toughness, and durability suitable for structural and load‑bearing assemblies.
The non‑serrated flange provides an integrated bearing surface that evenly distributes clamp load without biting into the mating material, making these bolts ideal for applications where surface protection, reusability, or controlled torque characteristics are important. The plain, uncoated finish offers maximum material integrity and is well suited for controlled environments or applications where additional coatings or finishes may be applied after installation.
Engineered for consistency and performance, DIN 6921 Class 8.8 Non‑Serrated Hex Flange Bolts are commonly used in machinery, equipment manufacturing, enclosures, automotive components, and industrial assemblies. The integrated flange eliminates the need for a separate washer while providing stable load distribution and clean installation. Available in a wide range of metric diameters and lengths, these plain‑finish bolts deliver dependable fastening strength and precision for OEM production, maintenance, and repair operations.
