Metric Class 8 Nylon Flange Locknut, Non Serrated, DIN 6926, Zinc CR+3
Our Metric Class 8 Nylon Flange Locknuts manufactured to DIN 6926 with a Zinc CR+3 finish are designed to provide reliable locking performance and corrosion resistance for general‑purpose mechanical and industrial applications. Produced from carbon steel and heat‑treated to property class 8, these locknuts offer dependable strength suitable for medium‑duty assemblies where vibration resistance is required.
The non‑serrated flange serves as an integrated washer, evenly distributing load across the mating surface without damaging coatings or softer materials. A nylon insert locking element creates prevailing torque that helps prevent loosening caused by vibration or movement, while still allowing repeated installation and removal. The Zinc CR+3 (trivalent chromium) plating provides corrosion protection and a clean, bright finish suitable for indoor and light‑to‑moderate outdoor environments while meeting current environmental compliance standards.
Designed for installation efficiency and consistent performance, DIN 6926 Class 8 Non‑Serrated Nylon Flange Locknuts with Zinc CR+3 are commonly used in machinery, automotive components, equipment manufacturing, enclosures, and maintenance applications. The flange design eliminates the need for a separate washer, reducing part count and simplifying assembly, while the nylon insert ensures secure locking under normal service conditions. Available in a wide range of metric thread sizes, these locknuts provide a practical fastening solution for OEM production, repair, and general industrial use.
