Overview
DIN 6923 has a regular hexagonal shape with a threaded connection in the center; the nut has special notches on the outside that cut into the metal when tightened.
Strength class DIN 6923
The strength class of a DIN 6923 nut is the maximum applied force at which the nut begins to fracture. DIN 6923 nuts are manufactured in strength classes from 6 to 12. From strength class 8, the nut is considered high-strength.
Materials for the manufacture of DIN 6923 spur nuts
DIN 6923 is manufactured in the following materials:
- Steel, which can be optionally coated with hot-dip galvanized, ordinary galvanized, yellow galvanized and zinc plated
- Stainless steel (A2, A4) does not need to be coated
Application area of the nut DIN 6923
DIN 6923 is used in industrial construction, machine tool and instrumentation, etc.
In addition, the range of applications directly depends on the material of manufacture and the coating of the product:
- Galvanized steel offers good corrosion protection if the fastener is to be used in aggressive environments.
- Stainless steel allows the fasteners to be used at high temperature extremes and in aggressive and humid environments.
