Cold-Forged Carbon Steel Nylon Nut DIN 985/982 Vibration-Proof Locking for Automotive Assemblies

Precision Vibration Resistance:

• The internal PA66 nylon ring provides a prevailing torque that prevents the nut from backing off under high-frequency vibrations or rotational forces, eliminating the need for spring washers.

Enhanced Reusability:

• The high-elasticity nylon insert is designed to return to its original shape after removal, allowing the nut to be reused multiple times (within elastic limits) without significant loss of locking torque.

Cold-Forged Strength:

• Our nut bodies are produced through high-speed cold forging, resulting in superior grain flow and higher tensile strength compared to machined alternatives.

Dual Standard Compliance:

• Fully compliant with both DIN 985 (low profile) and DIN 982 (heavy-duty) specifications, providing versatility for various space and load requirements.

Protection for Bolt Threads:

• The nylon collar acts as a secondary seal against moisture and contaminants, reducing the risk of thread corrosion and galling during long-term service.

Q: What is the maximum temperature a nylon nut can withstand?

1. A: The standard PA6/PA66 insert is rated for continuous use up to 120°C. For higher temperatures, we offer metal-insert locking nuts.

Q: Can I reuse a nylon nut after it has been removed?

2. A: Yes, but the locking torque decreases slightly with each use. For critical safety applications, we recommend using a new nut.

Q: Do you provide Material Test Reports (MTR)?

3. A: Absolutely. Every shipment is accompanied by a full 3.1 MTR, including chemical analysis and mechanical testing.

Q: What is the MOQ for a custom size?

4. A: Generally, 1000 pieces per size, but this varies based on the complexity of the specification.

Q: Do you support third-party inspections?

5. A: Yes, we regularly work with SGS, Bureau Veritas (BV), and TÜV for pre-shipment inspections.
