Steel 10.9 Hex Bolt Geomet
This is a completely chrome-free rust prevention treatment that is laminated in dozens of layers by heating metal zinc flakes in a curing oven. 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 during fastening to aluminum. The head shape is hexagonal. *Geomet is a registered trademark of NOF Metal Coatings Co., Ltd.*

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. 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 by possessing the sacrificial protection effect of zinc, it can prevent galvanic corrosion that occurs when fastening to aluminum. It complies with RoHS/ELV directives. *Geomet is a registered trademark of NOF Metal Coatings Co., Ltd.
