Auto Standard Q198 M5-M10 Bearing Surface Three Point Welding Screw

Auto standard Q198M5-M10 bearing surface three-point welding screw.

Description

Welding screw is also called energy storage screw, electric bolt welding stud, or planting welding nail, etc.

The full name of yellow zinc plating is galvanized golden yellow passivation.
The solution used for passivation is composed of three basic components: chromic acid, sulfuric acid, and nitric acid, but the ratio is slightly different, and there is no difference in the composition and anti-corrosion ability of the passivation film.

Zinc plating refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and rust prevention. The main method used is hot-dip galvanizing.

The zinc coating is thick, with fine crystals, uniformity and no porosity, and good corrosion resistance; the zinc coating obtained by electroplating is relatively pure, and corrodes slowly in the mist of acid, alkali, etc., which can effectively protect the fastener matrix. The zinc coating is chromic acid After passivation, it will form white, colorful, army green, etc., which is beautiful and decorative. Because the galvanized layer has good ductility, it can be formed by cold punching, rolling, bending, etc. without damaging the coating .
