A set screw is a metal fastener that looks like a rod with a full thread. The main difference between the set screw and other types is the absence of a head or cap. At its ends, there are special protrusions or recessed slots that strengthen the connection and fixation of structural parts. The DIN 923 screw is a stepped set screw with a cylindrical head and a straight slot. This screw has two threads of different diameters, which allows it to connect parts of different thicknesses.
Fastening group DIN 923
DIN 923 set screws belong to the stainless steel fasteners group.
Materials for the manufacture of DIN 923 screws
DIN 923 set screws are manufactured in the following materials:
- Steel, which can optionally be coated with zinc. Zinc protects against corrosion if the fasteners are to be used in aggressive environments.
- Stainless steel. Steel grade A1 allows the fasteners to be used at significant temperature changes and in aggressive and humid environments.
Areas of application for DIN 923 screws
The use of DIN 923 screws can be found in many industries, including construction, mechanical engineering and electrical engineering. They can be used to connect two parts or to fasten parts to a base.
