High Temp Nylon Lock Nuts
We follow ISO 16130 for transverse vibration testing. Take an M10 nylon lock nut as an example. After 2000 vibration cycles, the residual clamp force stays at ≥75%. A regular nut stays below 20%. The size range is M2 to M48. The nylon ring is PA66 (polyamide 66). It works from -40°C to +120°C.
Stop Loosening with Our Nylon Lock Nuts
Do you need a nut that locks well but does not hurt bolt threads? A regular nut shakes loose. Metal lock parts scratch the bolt. Our High Temp Nylon Lock Nuts make a good balance. The top has a nylon ring. The ring is slightly smaller than the thread. When the bolt goes in, the nylon deforms and hugs the thread. We are a Shanghai factory. We have made fasteners for 20 years.
Check Our Vibration Test Data and Temperature Range
We follow ISO 16130 for transverse vibration testing. Take an M10 nylon lock nut as an example. After 2000 vibration cycles, the residual clamp force stays at ≥75%. A regular nut stays below 20%. The size range is M2 to M48. The nylon ring is PA66 (polyamide 66). It works from -40°C to +120°C. The nylon ring is molded into a groove on the nut body. The axial pull-out force is ≥100 N. The ring will not come off. We offer stainless steel SUS304, carbon steel SWRCH35K or 10B21, and aluminum 6061-T6. Carbon steel grade is 8 or 10 per ISO 898-2. Surface finish includes cleaning, zinc plating, or Dacromet. Zinc plating comes in white or yellow. Salt spray test lasts 48-72 hours. Aluminum can get anodizing in black or natural color. Dacromet gives 500+ hours of salt spray for high corrosion areas.

Why Our R&D and Sample Policy Help You
We have our own R&D team. You can share your special needs. We will help solve your technical problems. Free samples are ready for stock items. The nylon ring touches the thread elastically. It does not scratch the bolt like metal lock parts. This is good for stainless steel or coated bolts. You can use standard wrenches or sockets. You do not need special tools. The torque is similar to regular nuts. Add 10-15% to overcome nylon resistance. Mass production takes 2-3 weeks for standard parts. Custom products take 4 weeks. Repeat orders are even faster.
The entire product line is fully customizable.
