DIN 84 screw This type of stainless steel fastener looks like an ordinary metal rod with a head at one end that transmits torque and an external thread at the other end. DIN 84 is an analog of GOST 1491-80.
DIN 84 strength class
DIN 84 screws are made of steel of strength class 4.8.
DIN 84 fastening group
Depending on the material of manufacture, DIN 84 screws are divided into groups:
- Brass fasteners
- Stainless steel fasteners
- Polyamide fasteners
Materials of manufacture of DIN 84 screws
DIN 84 screws are made from a variety of materials:
- Steel, which can be additionally coated with zinc and yellow zinc
- Brass
- Polyamide
- Stainless steel A1, A2, A4
Field of application
It is widely used in mechanical engineering, instrumentation, construction, and the automotive industry.
The scope of application also directly depends on the material of manufacture and the coating of the screw:
- The zinc coating on steel protects against corrosion if the fastener is to be used in aggressive environments.
- Brass screws are used if the system is subjected to frequent dynamic, vibration, and cyclic loads.
- Stainless steel allows the fasteners to be used at significant temperature fluctuations and in aggressive and humid environments.
