Steel hexagon socket bolt (cap bolt) zinc trivalent chromate black.
This is a bolt with a hexagonal hole. It is tightened using a hexagonal rod wrench (hex key). By applying a zinc and nickel alloy electroplating to the base material, it offers superior corrosion resistance compared to conventional zinc plating in saltwater and outdoor exposure. It also has excellent heat resistance and is characterized by being hard and resistant to scratches.

Applications/Examples of results
Steel is widely used as a material for screws due to its easy availability, strength, and toughness. Based on carbon steel, which primarily consists of iron (Fe) and carbon (C), alloy steels that have undergone heat treatment or have additives such as chromium and molybdenum are used according to applications, considering shape, strength, and corrosion resistance. Trivalent chromium zinc alloy plating, applied over a base of zinc and nickel alloy electroplating, provides a coating with excellent corrosion resistance in saltwater and outdoor exposure compared to conventional zinc plating. Additionally, due to its excellent heat resistance and hardness that makes it difficult to scratch, this coating is suitable for corrosion protection of automotive engine peripheral parts.
