Built with an all-metal prevailing torque locking mechanism, this design creates additional friction between the nut and mating thread to help resist self-loosening under vibration and dynamic loads. Unlike nylon insert lock nuts, no polymer locking ring is used.
SENOTECH supplies DIN 980 all-metal lock nuts, also commonly searched as prevailing torque nuts, metal lock nuts, all-metal self-locking nuts and high temperature lock nuts, for machinery manufacturers, automotive suppliers, industrial equipment companies and fastener distributors.
All-Metal Locking for Demanding Applications
The metal locking design makes these nuts particularly useful where conventional nylon insert lock nuts may not be appropriate because of elevated operating temperatures or demanding service conditions.
Typical applications include:
- Automotive assemblies
- Heavy machinery
- Industrial equipment
- Agricultural machinery
- Construction equipment
- Vibration-prone connections
- High-temperature fastening
- Mechanical engineering
DIN 980 vs DIN 985 Lock Nuts
DIN 985 nylon insert lock nuts use a polymer insert to generate prevailing torque, while DIN 980 uses an all-metal locking principle.
For buyers selecting between the two, operating temperature, vibration, required property class and assembly conditions should be considered.
SENOTECH can supply both nylon insert lock nuts and all-metal prevailing torque nuts, allowing buyers to source different locking solutions within one fastener package.
Materials & Finishes
Available options include carbon steel and stainless steel, with finishes such as:
- Zinc Plated
- Yellow Zinc
- Black
- Phosphate
- Zinc Flake
- Plain Stainless Steel
- Customized Coatings
Property classes and coatings can be supplied according to application and purchasing specifications.
Bulk & OEM Supply
For fastener distributors and OEM manufacturers purchasing all-metal lock nuts in bulk, SENOTECH supports different metric thread sizes, property classes, materials, coatings and export packaging.
Fine threads and project-specific requirements can also be evaluated according to drawings or technical specifications.
