Product Description
Detailed Specifications & Features
Blue Zinc Plated Hexagon Lock Nut - DIN985 Nylon Insert
This DIN985 prevailing torque hexagon lock nut is made of carbon steel and finished with a blue zinc anti-corrosion coating. The nylon insert in the crown locks the nut against vibration, giving reliable, reusable fastening for M4-M24 threaded joints.
Key Selling Points
- Blue Anti-Corrosion Coating: The blue zinc plating forms a dense, uniform layer that resists rust, humidity and mild chemicals. It passes a 96 hour salt spray test, keeping the nut clean and protected in outdoor and humid conditions.
- Nylon Insert Locking: A nylon ring in the top of the nut grips the bolt thread to generate prevailing torque, effectively preventing loosening under vibration while still allowing easy disassembly.
- Stable Carbon Steel Body: Made from carbon steel with controlled hardness for consistent clamping load and a clean, burr-free thread in sizes M4-M24.
