Suppliers of dacromet coated screws, check difference between Dacromet Coating Vs Zinc Plating or Galvanized Process

Coatings are used on fasteners to improve their performance, while also increasing their longevity and improving their resistance to corrosion. One such method of improving the fastener’s performance is by using dacromet finish bolts in any given application. An inorganic material, the production of Dacromet is made by melting zinc and aluminum flakes. The flakes are connected by chromate. Most dacromet coated fasteners suppliers recommend the use of this inorganic finish simply because of the material, which acts firmly because of its adhesive nature. 

The use of dacromet coated bolts is considered to be ideal for applications that have high corrosion resistance requirements. Since the finish is an adhesive layer, dacromet coated stud bolts are known to have a thin layer, in terms of their thicknesses. This is why this coating is used in the automotive industry, especially because the fastener is used to hold various elements in place.  Another characteristic of the dacromet coated screws is that the coating exhibits good heat resistance while offering a low friction coefficient.

The danger of hydrogen embrittlement does not exist. The dacromet coating process takes place in an aqueous media, where the application of the layer takes place with the dispersion of chromate zinc flakes in an aqueous dip-spin process. The coated layer is then dried, followed by subsequent burning at a temperature of 300 °C. The Dacromet® Coated Fasteners also exhibit superior resistance to mechanical damage.
