DIN 985 Yellow Dichromate Hexagon Lock Nut with Nylon Insert – M10 x 1.5 – Class 8 – Gold – Prevailing Torque Self‑Locking Nut

Self‑locking hex nut manufactured to DIN 985 (ISO 10511). Nylon insert provides prevailing torque that resists loosening under vibration. Yellow dichromate finish offers enhanced corrosion resistance and a gold appearance. Strength class 8 matches property class 8.8 bolts. Suitable for machinery, automotive, and any bolted joint subject to dynamic loads.


Product Applications

  1. Automotive chassis, suspension, and engine mounts

  2. Industrial machinery and vibrating equipment

  3. Agricultural implements and off‑road vehicles

  4. Pumps, compressors, and motor mounts

  5. Conveyor systems and material handling

  6. General maintenance where vibration is present


Product Advantages

  1. Nylon insert locks without damaging bolt threads – reusable within limited cycles

  2. Prevailing torque design – resists loosening from shock and vibration

  3. Yellow dichromate plating – up to 200+ hours salt spray protection

  4. Class 8 strength – matches the most common bolt grade (8.8)

  5. Easy assembly – installs with standard tools; no adhesive or wire required

  6. Cost‑effective alternative to all‑metal lock nuts

  7. Metric coarse thread – quick engagement and wide availability


Product Functions

  1. Nylon ring compresses against bolt threads to create friction – generates prevailing torque

  2. Resists rotation caused by vibration or cyclic loading

  3. Maintains clamp load over extended service periods

  4. Allows adjustment and re‑torquing if needed

  5. Provides locking action without deforming threads – bolt remains reusable


Packing & Delivery

  • Packing: Bulk cartons or plastic bags + cartons; custom packaging available

  • Delivery: 7–15 days for stock; 15–20 days for custom orders


FAQ

Q: Can this nut be reused?
A: Yes, but the nylon insert loses its locking effectiveness after several removals – new nuts are recommended for critical applications.

Q: What is the maximum temperature for this nut?
A: The nylon insert is rated up to +120°C; for higher temperatures, use all‑metal lock nuts (e.g., DIN 980).

Q: Does this nut require a washer?
A: Not necessary, but a flat washer can be used under the nut to distribute load if the bearing surface is soft.

Q: What bolt grade should this be used with?
A: Class 8 nuts are designed for property class 8.8 bolts.
