Product Name: Nylon Self-Locking Nut
Product Overview
Anti-loosening nuts are a type of fastener with a special anti-loosening structure, specifically designed for vibration, shock or dynamic load environments, and can effectively prevent connection loosening. It provides more reliable anti-loosening performance than ordinary nuts through principles such as mechanical deformation, friction enhancement or elastic locking, and is widely used in key fields such as automobiles, railways, aviation, mechanical equipment and building structures.
Product Features
Mainstream anti-loosening technologies:
- Nylon insert type: The top is equipped with a nylon ring (NYLOC). When screwed in, it undergoes elastic deformation to form continuous friction
- All-metal locking type:
Double nut structure (DIN 980/981)
Flange serrated design (DIN 6927)
Elliptical deformed thread (eccentric locking)
- Chemical adhesive type: Pre-coated anti-loosening adhesive (such as Loctite technology)
2. High-strength material:
Carbon steel (Grade 8 / Grade 10 / Grade 12)
Stainless steel (A2-70/A4-80)
Special alloys (titanium alloys, Inconickel, etc.)
3. Surface treatment:
Galvanizing (blue and white/colored zinc)
Dacromet (Corrosion-resistant)
Nickel plating (wear-resistant)
Oxidation and blackening (rust prevention)
4. Performance Parameters:
- Vibration test: Passed the DIN 65151 standard
- Locking torque: 30-50% higher than that of ordinary nuts
- Operating temperature: Nylon type (-40℃ to +120℃), all-metal type (-60℃ to +300℃)

Selection Guide:
1. Vibration level selection:
- Slight vibration: Nylon lock nut
- Moderate vibration: All-metal double nuts
- Severe vibration: Eccentric thread + flange serrated compound type
2. Environmental adaptability:
- Corrosive environment: 316 stainless steel + Dacromet
- High-temperature environment: 12.9 grade alloy steel
- Electromagnetic sensitivity: Non-metallic locking structure
3. Installation Precautions:
Nylon lock nuts must not be reused more than three times
Pre-coated nuts need to be assembled within 24 hours
Use a torque wrench to ensure the correct preload
