Self-locking high nut DIN 982

   DIN 982 is a nut used in connection elements that are constantly exposed to dynamic loads, especially vibration, which can cause loosening. The contraction in DIN 982 is achieved by a nylon ring in which the thread is cut during tightening.

Strength class DIN 982

     The strength class of a DIN 982 nut is the maximum applied force at which the nut begins to fracture. DIN 982 nuts are manufactured in strength classes 8 and 10. From strength class 8 onwards, the nut is considered high-strength.

DIN 982 fastening group

     The nuts are divided into groups according to their material of manufacture:

• High-strength fasteners - nuts made of steel of strength class 8 and above
• Stainless fasteners - nuts made of stainless steel.

Materials for the manufacture of DIN 982 nuts

     DIN 982 is manufactured in the following materials: 

• Steel, which can optionally be coated with galvanized and plain (white) zinc.
• Stainless steel (A2, A4) does not need to be coated.

Areas of application for DIN 982 nuts
