This is DIN 980‑V standard all‑metal hexagon Stover prevailing‑torque lock nut. One end of the nut is clinched and deformed. The distorted threads build permanent friction damping against bolt threads for reliable self‑locking performance with no nylon insert. The zinc‑plated finish delivers rust‑proof capacity. Capable of high‑temperature resistance, it is the ideal anti‑loosening fastener for vibrating and harsh‑temperature industrial and automotive components.

Key Features：

1. All‑metal Stover clinched‑lock structure The deformed clinched end creates prevailing torque on bolt threads. Free from plastic nylon inserts, it stays functional under high‑temperature conditions without ageing‑caused failure.
2. Blue‑white zinc‑plated anti‑corrosion coating Smooth and uniform plating resists oxidation and moisture corrosion with strong coating adhesion.
3. Precision‑engineered internal threads Manufactured to DIN 980‑V specifications. Well‑formed threads maintain stable locking torque after repeated disassembly.
4. Integrated hex‑shaped body Standard hexagonal outer profile fits spanner and socket tools for straightforward installation.
5. Heavy‑duty carbon‑steel construction Hardened steel body features outstanding shock‑resistance and wear‑resistance for long‑term anti‑loose performance under continuous vibration.

Common Applications：

Widely used in automobile chassis fittings, construction machinery, rail‑transit spare parts, wind‑power equipment, high‑temperature machinery, pipe fasteners, motor‑bike components, new‑energy facilities, mining equipment and heavy‑duty steel‑structure assemblies where nylon‑free high‑heat resistant locking nuts are required.
