DIN 6908 Screw with Captive Clamping Washer

DIN 6908 covers screws with captive clamping washers. The washer increases the contact area on the material, reduces pressure, and prevents cracking. The clamping washer also increases joint strength and prevents self-loosening. This type of fastener is used for assembling machine, mechanism, and unit components, and is in demand in industry.

Materials and coatings

The screws are made of carbon steel with electroplated zinc coating for corrosion protection. A version made of acid-resistant stainless steel grades A2 and A4 with increased resistance to environmental impact is also available.

Product specifications:

• Hexagon head for tightening and loosening with a wrench.
• Partial metric thread for fixing in a hole or use together with a nut.
• The closest equivalent is manufactured to DIN 6900.

The fasteners are used in the assembly of metal structures, in the automotive industry, production of special equipment, and other industries.
