Product Description

DIN931-1 ISO EN 4014 Hexagon Head Bolts Partially Threaded Blackened Carbon Steel/Alloy Steel Class 8.8 10.9 12.9

Advantages:

  1. Corrosion Resistance: The blackening process creates a dense oxide film on the bolt surface, providing excellent corrosion resistance and preventing rusting in damp or corrosive environments.

  2. Wear Resistance: Blackened bolts exhibit increased surface hardness, improving their wear resistance and enabling them to maintain good performance in frequently rubbed environments.

  3. Aesthetic Appeal: The blackened surface of the bolts gives them a unique and attractive appearance, making them suitable for use in applications where aesthetics are important.

  4. Cost-Effectiveness: Blackening is a cost-efficient surface treatment method, offering better value for money compared to other surface treatments such as zinc plating or painting.

Characteristics:

  1. Uniformity: The blackened surface of the bolts is evenly colored, with no significant color differences or spots, ensuring an overall aesthetic appeal.

  2. Stability: The oxide film formed during blackening is stable and does not easily peel off or discolor, guaranteeing the durability of the bolts.

  3. Environmental Friendliness: The blackening process does not generate harmful substances and meets environmental protection requirements.

Applications:

DIN 931-1 blackened bolts are widely used in various fields such as mechanical equipment, architectural structures, automotive manufacturing, and more. They are particularly common in applications where corrosion resistance, wear resistance, and aesthetics are critical. For example, in chemical equipment, bolts with excellent corrosion resistance are needed due to the corrosive nature of the media. In automotive manufacturing, bolts with good wear resistance are required for components like engines and transmissions. And in architectural structures, bolts with high strength and stability are essential to bear significant loads.
