Flange Lock Nut
We follow ISO 16130 for transverse vibration testing. Take an M10 flange lock nut as an example. After 3000 vibration cycles, the residual clamp force is ≥80%. This is even better than a nylon lock nut. The size range is M3 to M20. The flange serrations are radial and even.
Skip the Washer with Our Flange Lock Nut
Do you want faster assembly? You do not want to add a separate washer. Our Flange Lock Nut combines the flange and nut into one part. The flange bottom has radial serrations. When you tighten, the serrations bite into the part surface. This gives a mechanical lock. We are a Shanghai factory. We have supplied fasteners for 20 years.
Check Our Vibration Test Data and Serration Design
We follow ISO 16130 for transverse vibration testing. Take an M10 flange lock nut as an example. After 3000 vibration cycles, the residual clamp force is ≥80%. This is even better than a nylon lock nut. The size range is M3 to M20. The flange serrations are radial and even. The tooth count is 8 to 16 based on the size. The tooth height is 0.15 to 0.25 mm. The flange and nut body are cold headed as one piece. There is no risk of separation. We offer stainless steel SUS304 or 316 and carbon steel SWRCH35K or SCM435. Carbon steel grade is 8, 10, or even 12 per ISO 898-2. The flange outer diameter is 30-40% larger than a standard hex nut bearing surface. This lowers the stress on the part surface. It stops soft materials like aluminum or plastic from denting. The tooth tip hardness after heat treatment is HV 400-500. It can bite into steel or aluminum sheets at ≤HRB 70.

Why Our Follow-up Service and Design Matter
We have order trackers. They follow every step from your first price inquiry to delivery at your warehouse. If your customer has assembly problems, we have a person to talk and solve it. Warranty depends on the industry. We have many product types. We can talk about the details. The serrations will scratch the part surface on first use. Do not reuse it in the same spot. If you need to remove and lock again, use a new nut or add thread locker. You can use a standard socket wrench. No extra washers are needed. This reduces part types and speeds up assembly.
The entire product line is fully customizable.
