Pioneering the fastener industry with unwavering dedication since 1985, for a remarkable span of over 39 years.
Standard (GB / DIN / ISO / UNI / JIS / GOST / ANSI / ASTM ); And Tailor-made Non-standard crafted meticulously according to your unique designs.
Nylon locking nut is a special anti-loosening fastener. By embedding a nylon ring (PA66 or PA6 material) at the top of the nut, the elastic deformation of nylon generates friction resistance to prevent the nut from loosening due to vibration or impact. This design makes it widely used in the fields of automobile, aerospace, machinery manufacturing, etc.
1. Structure and working principle of nylon locking nut
(1) Structural characteristics
Metal nut base: usually carbon steel or stainless steel (such as 304/316), providing the main strength.
Nylon locking ring: The nylon ring (mainly PA66) embedded at the top of the nut, the thickness of which accounts for about 1/3 of the nut height.
Standard thread: in accordance with ISO, DIN and other standards (such as M6, M8, etc.).
(2) Anti-loosening principle
Elastic deformation: When the bolt is screwed in, the nylon ring is squeezed and deformed, generating radial pressure.
Friction locking: The friction between nylon and thread is significantly increased (3-5 times higher than ordinary nuts).
Adaptability: Even if the thread is slightly worn, nylon can still maintain contact pressure.
2. Main types and standards
(1) Classification by appearance
Type Features Standard example
Hexagonal nylon lock nut Universal type, wrench installation DIN 985, ISO 7040
Flange nylon lock nut With flange surface, dispersed pressure to prevent loosening DIN 6923
Thin nylon lock nut Low height, used in space-constrained occasions ISO 7035
(2) By material grade
Nylon ring material: PA66 (temperature resistant 120°C), PA46 (temperature resistant 150°C), PEEK (temperature resistant 250°C, high-end application).
Metal matrix: carbon steel (grade 4.8/8.8), stainless steel (A2/A4), titanium alloy (aerospace)
