Overview
Strength class DIN 6331
The strength class of a DIN 6331 nut is the maximum applied force that causes the nut to fracture. Din 6331 nuts are manufactured in strength class 10. From strength class 8 onwards, the nut is considered high-strength.
DIN 6331 fastening group
Depending on the material of manufacture, DIN 6331 nuts are divided into groups:
- Stainless fasteners
- High-strength fasteners.
Materials for the manufacture of DIN 6331 nuts
DIN 6331 nuts are made of the following materials:
- High-strength structural alloy steel of strength class 10. The high strength class 10 allows the nuts to be used in highly loaded connections. Which can be additionally coated with zinc. Zinc protects against corrosion if the fasteners are to be used in aggressive environments.
- Stainless steel grades A2 and A4. Allows the bolts to be used at significant temperature drops and in aggressive and humid environments
Application range of DIN 6331 nuts
Flanged nuts have become popular in industrial sectors: they help reduce the cost of a threaded connection while making it more reliable. They are used in mechanical engineering, machine tool building, instrumentation, and other areas, including the production of automobiles and special equipment. These fasteners can be used in conjunction with thin sheet materials to protect them from damage.
