DIN 6905 Screw with Captive Spring Washer

The screw with captive spring washer is manufactured to DIN 6905. This fastener is designed for secure fixing of components: the spring washer increases the contact area and prevents cracking on thin sheet material. Screws of this type are used in machine building, instrument engineering, automotive manufacturing, other branches of industrial production, and in the assembly of metal structures. They provide a connection resistant to loosening.

Manufacturing features

The main material for screws with captive washer is high-strength carbon steel, with corrosion protection provided by a zinc layer applied by electroplating. Fasteners for corrosive environments are made from stainless steel A2 and A4. Fastener characteristics:

• The head has a hexagon shape for tightening with a wrench.
• A partial metric thread is applied to the metal shank.
• The closest equivalent is manufactured in accordance with DIN 6906.
