DIN 982 / DIN 985 Class 8.8 Metric Nylon Insert Locknut with Clear Zinc Cr3 Plating
The DIN 982 and DIN 985 Class 8.8 Metric Nylon Insert Locknuts with Clear Zinc Cr3 Plating are high-performance fasteners designed for secure, vibration-resistant connections in demanding industrial, automotive, and structural applications. These locknuts are engineered to provide excellent resistance to loosening under dynamic loads while offering moderate corrosion protection.
Specifications:
Both DIN 982 and DIN 985 define all-metal hex locknuts with a nylon insert collar. The primary difference is in height—DIN 982 is higher than DIN 985, offering additional thread engagement and locking power. Made from Class 8.8 medium carbon steel, these locknuts are heat-treated for strength and durability.
The nylon insert (polyamide) acts as a prevailing torque element, gripping the mating thread to resist vibration-induced loosening. This makes them reusable a limited number of times without compromising the locking function.
The Clear Zinc Cr3 plating provides a protective coating that resists corrosion, abrasion, and oxidation. Chromium-3 (Cr3) is RoHS compliant, environmentally friendly, and safer for use in sensitive applications, unlike traditional Chromium-6 finishes. This plating enhances the fastener’s performance in indoor and mildly corrosive environments.
Available in a wide range of metric thread sizes (M5 to M30), these locknuts comply with ISO 7040 / ISO 10511 standards and are compatible with a broad array of standard bolts and screws.
Applications:
-
Automotive assemblies (suspension, engine mounts, brake systems)
-
Construction and infrastructure (steel framing, decking)
-
Heavy machinery and industrial equipment
-
Electromechanical and HVAC systems
-
Renewable energy installations (solar panel racking, wind turbines)
DIN 982 and DIN 985 Class 8.8 Nylon Insert Locknuts with Clear Zinc Cr3 Plating deliver robust locking strength, corrosion resistance, and are an ideal solution for high-vibration, load-bearing environments where reliability is essential.
