Product Description

DIN931-1 ISO4014 Hexagon Head Bolts Partially Threaded Dacromet Silver-Gray Carbon Steel/Alloy Steel Class 8.8 10.9

Advantages of DIN 931-1 Bolts with Dacromet Coating

  1. High Corrosion Resistance: The Dacromet coating provides excellent corrosion resistance, especially in harsh environmental conditions such as high humidity, high salinity, or chemical corrosion.

  2. High Temperature Stability: The Dacromet coating remains stable at relatively high temperatures (up to 300°C) without deteriorating like some other coatings.

  3. Good Adhesion and Abrasion Resistance: The Dacromet coating exhibits strong adhesion to the base material and also possesses good abrasion resistance.

  4. Environmental Friendliness: Compared to traditional zinc plating or paint coatings, the Dacromet coating is more environmentally friendly during production and usage as it does not contain harmful substances like chromates.

Characteristics of DIN 931-1 Bolts with Dacromet Coating

  1. Uniformity: The Dacromet coating can uniformly cover the entire surface of the bolt, including hard-to-reach corners and crevices.

  2. Color: The Dacromet coating typically has a silver-gray or silver-white appearance, making the bolts visually easier to identify.

  3. Versatility: The Dacromet coating is suitable for various metal substrates such as steel, copper, aluminum, and more.

Applications of DIN 931-1 Bolts with Dacromet Coating

  1. Automotive Industry: Bolts are extensively used in automotive manufacturing, especially in chassis, engine, and body structures. The Dacromet coating provides the necessary corrosion protection to ensure long-term reliability of vehicles under various climatic conditions.

  2. Construction and Bridge Engineering: In construction and bridge projects, bolts are used to connect steel structures and concrete components. The Dacromet coating protects these bolts from environmental and chemical corrosion.

  3. Marine Engineering: Metal components are prone to corrosion from seawater and salt spray in marine environments. The Dacromet coating offers essential protection to bolts and other metal components to ensure their long-term stability in harsh conditions.

  4. Electrical and Electronic Equipment: Bolts are used to connect and secure various components in electrical and electronic devices. The Dacromet coating prevents the bolts from electrochemical corrosion, ensuring stable operation of the equipment over a long period.

In summary, DIN 931-1 bolts with a Dacromet coating exhibit excellent corrosion resistance, high temperature stability, adhesion, abrasion resistance, and other advantages, making them suitable for various environments and industries.
