Steel hexagon socket bolt (cap bolt) Geomet
This is a bolt with a hexagonal hole. It is tightened using a hexagonal rod wrench (hex key). The corrosion treatment involves layering metal zinc flakes in a heated oven, resulting in dozens of layers. Since it is a water-based solution, it is completely chrome-free. Environmental considerations are also taken into account during the manufacturing process. The film thickness is 8 microns, and it excels in corrosion resistance and heat resistance. The Geomet coating has a corrosion potential close to that of aluminum, which can prevent galvanic corrosion that occurs when fastening to aluminum. *Geomet is a registered trademark of NOF Metal Coatings Co., Ltd. *It is assumed that domestically produced wrenches are used for tightening.

Applications/Examples of results
Steel is widely used as a steel material for screws due to its easy availability and strength. Based on carbon steel, which primarily consists of iron (Fe) and carbon (C), alloy steels are used that have undergone heat treatment or have additives such as chromium and molybdenum, depending on the application, shape, strength, and corrosion resistance. Geomet treatment is a completely chrome-free rust prevention process formed by layering several dozen layers after immersion in a dispersion aqueous solution of metallic zinc flakes and heating in a curing furnace. The film thickness is about 8 microns, providing excellent corrosion and heat resistance. The Geomet coating has a corrosion potential close to that of aluminum and can prevent galvanic corrosion that occurs when fastening to aluminum due to the sacrificial protection effect of zinc. It complies with RoHS/ELV directives. *Geomet is a registered trademark of NOF Metal Coatings Co., Ltd.
