Bolt DIN 6921 M8x16 10,9 zinc flake black

Flanged bolts are widely used in places where the bearing area of ​​the bolt needs to be increased. Often to prevent self-unscrewing.

Area of ​​use Bolt DIN 6921 is used in wet rooms and in the open air, structures in solar installations.

The material of manufacture is high-strength structural alloy steel. The high strength class 10.9 allows the use of bolts in highly loaded connections.

Coating: black zinc cloth.

Main characteristics of this coating:

• Organic black topcoat;
• Excellent corrosion protection;
• High hiding power on silver and black base coatings;
• Attractive uniform black appearance;
• Very good chemical resistance; increased UV resistance;
• Excellent adhesion, i.e. the coating does not peel, crack or flake even under mechanical stress or chemical attack;
• Integrated lubricant component for controlled friction characteristics;
• No hydrogen embrittlement;
• Excellent corrosion resistance in NSST and cyclic corrosion tests.
