Stainless Steel All-Metal Lock Nut DIN 980M
Product Overview
All-metal lock nut DIN 980M is a high-strength, self-locking nut with a one-piece metal construction that ensures excellent resistance to vibration and loosening under high-stress conditions. Manufactured in accordance with DIN 980M standards, these nuts do not rely on nylon inserts or adhesives, making them exceptionally robust and reliable in both high-temperature and corrosive environments. The self-locking mechanism operates via localized deformation of the threads, maintaining consistent tightening torque over time. These nuts are ideal for critical load applications where secure and long-term fastening is essential.
Flybear Fastener ensures superior product reliability and mechanical performance for our stainless steel DIN 980M lock nuts, making them a trusted choice across various industries requiring premium fastening solutions.

Material Description & Manufacturing Process
Stainless steel, specifically grades A2-70 and A4-80, is the primary material used in producing the all-metal lock nut DIN 980M. A2-grade provides general corrosion resistance, while A4-grade offers enhanced resistance against acids and chlorides, ideal for marine and chemical applications.
The manufacturing process involves:
- Cold forming of the hex nut body
- Thread rolling to form internal threads
- Deformation of part of the top thread to induce prevalent torque
- Heat treatment for mechanical strength
- Surface passivation for corrosion protection
- Final quality inspection and packing
This meticulous process ensures the nuts meet the highest mechanical and technical standards.
Common Uses Across Key Industries
All-metal lock nut DIN 980M is widely implemented in:
- Automotive assemblies: engine mounts, suspensions, and chassis
- Rail and transportation infrastructure
- Wind turbines and renewable energy installations
- Petrochemical and offshore applications
- Aerospace components where dynamic loads are present
- Heavy machinery and construction equipment
Their ability to withstand vibration and environmental factors makes them ideal for critical fastening applications.
