DIN 6907 Screw with Captive Toothed Lock Washer

The European standard DIN 6907 applies to screws fitted with captive lock washers and special teeth. Thanks to this lock washer, the fastener protects the joint against spontaneous loosening under dynamic loads and vibration. The fastener reliably secures parts together, including thin-sheet materials. It is used in mechanical engineering for fastening parts of mechanisms and assemblies.

Features

The fastener of the DIN 6907 standard is made of standard-strength carbon steel with a layer of zinc applied by electroplating for corrosion protection. Stainless steel grades A2 and A4, which have increased resistance to acidic, chemically active environments, are also used.

Features and characteristics:

• The screw has a dome-shaped head fitted with a slot for driving.
• The metal shank has a partial metric thread.
• The underside of the washer is fitted with teeth for a stronger connection with the material.

The fastener is used in industry, in the assembly of metal structures, furniture production, and other sectors — for secure fastening of parts and components.
