Review
A self-contracting nut is a nut used in connection elements that are constantly exposed to dynamic loads, especially vibration, which can cause loosening. The contouring in DIN 985 is accomplished by a nylon ring in which the thread is cut during tightening.
DIN 985 strength class
The strength class of a Din 985 nut is the maximum applied force at which the nut begins to fracture. Din 985 nuts are manufactured in strength classes from 6 to 10. From strength class 8 onwards, the nut is considered high-strength.
DIN 985 fastening group
DIN 985 is made of high-strength steel and belongs to the high-strength fastener group.
Materials of manufacture:
DIN 985 is available in the following materials:
- Steel, which can be optionally coated with hot, normal, yellow and plate zinc.
Scope of application of the self-locking low nut DIN 985
Self-locking nut DIN 985 is used in mechanical engineering, construction, warehouse equipment, lifting equipment, agricultural machinery, tools, etc. In addition, the scope of application directly depends on the material of manufacture and the coating of the product:
- Galvanized steel provides good corrosion protection if the fastener is to be used in an aggressive environment.
