Blue and white zinc plated pin shaft

A blue and white zinc plated pin shaft is a type of fastener that is used to secure two or more objects together. The pin shaft is made of steel and is coated with a layer of zinc to protect it from rust and corrosion. The blue and white coloration is a result of the zinc plating process. The pin shaft is typically inserted through a hole in one object and then secured in place with a cotter pin or other type of locking mechanism. This type of fastener is commonly used in automotive, construction, and industrial applications.

These Pin shafts are white zinc plated to assemble scissors engineering equipment

Pin white zinc plating is a surface treatment technology that coats zinc on the surface of steel parts to prevent oxidation and corrosion. This processing technique is commonly used to make assembly components for scissors and other engineering equipment, such as pins. White zinc is a pure zinc with high corrosion resistance and aesthetics, so it is widely used in industry and construction. Using white zinc plating on pins can extend the service life of parts and improve the stability and reliability of equipment.
