   DIN 986 is a standard that describes a cap nut. This standard was developed by the German Institute for Standardization (DIN) and contains technical requirements for this type of fastener. A cap nut is a nut that covers a threaded part both decoratively and to protect the thread. DIN 986 can be used in places with limited space.

DIN 986 strength class


     The strength class of a DIN 986 nut is the maximum applied force at which the nut begins to fracture. DIN 986 nuts are made of steel of strength classes 6 and 8. Nuts of strength class 8 are considered high-strength nuts.

DIN 986 fastening group


     DIN 986 nuts are divided into groups depending on the material of manufacture:

  • High-strength fasteners 
  • Stainless fasteners


Materials for the manufacture of DIN 986 nuts


     DIN 986 nuts are made of the following materials:

  • Steel in strength classes 6 and 8. The high strength class 8 allows the nuts to be used in highly loaded connections. The steel can also be coated with zinc, which protects against corrosion if the fasteners are to be used in aggressive environments.
  • Stainless steel. Steel grade A2 allows the fasteners to be used at significant temperature changes and in aggressive and humid environments.


Application range of DIN 986 nuts


     This type of nut is used to connect parts that require protection against external factors such as moisture, corrosion or contamination. DIN 986 is used in playgrounds, sports equipment, etc.
