Metric Class 8 Hex Serrated Flange Locknut, DIN 6923, Plain
Our Metric Class 8 Hex Serrated Flange Locknuts manufactured to DIN 6923 with a Plain Finish are designed to provide reliable locking performance and load distribution in general‑purpose and medium‑duty metric fastening applications. Produced from carbon steel and heat‑treated to property class 8, these locknuts deliver dependable strength and durability for mechanical and industrial assemblies.
The serrated flange features integrated radial teeth that bite into the mating surface during installation, creating resistance to loosening caused by vibration and movement. This locking action eliminates the need for a separate washer while improving joint stability. The plain (uncoated) finish preserves full material integrity and is well suited for controlled environments, indoor applications, or situations where surface coatings are unnecessary or will be applied after installation.
Engineered for efficiency and vibration resistance, DIN 6923 Class 8 Plain Hex Serrated Flange Locknuts are commonly used in machinery, equipment manufacturing, automotive components, enclosures, and general industrial maintenance. The serrated flange provides consistent locking without additional hardware, while the Class 8 strength rating supports reliable clamp loads in everyday service conditions. Available in a wide range of metric thread sizes, these locknuts offer a practical fastening solution for OEM production, repair, and maintenance where simplicity, strength, and secure locking are required.
