Carbon steel can be used for lower or moderate duty fastening, while medium carbon steel and alloy steel are often selected for grade 8.8, 10.9, and 12.9 flange bolts. The correct choice depends on clamp load, mating material, service environment, and whether the bolt is used in automotive, structural, or machinery applications.<\/p>\n        <p>For high tensile flange bolts, heat treatment and thread quality should be controlled carefully. Buyers should state the required grade, test method, and whether the flange face must be serrated or smooth. For assemblies exposed to weather, coating performance should be discussed together with grade and torque requirements.<\/p>\n      <\/div>\n      <div>\n        <h2>Surface Finish Selection Guide<\/h2>\n        <p>Dacromet is a zinc-aluminum flake coating often used when buyers need corrosion resistance on high strength fasteners. It is not an electrolytic coating, which makes it a practical option for many high tensile bolt projects. Buyers comparing finishes can review XZ Fastener\u2019s <a href=\"https:\/\/xzfastener.com\/dacromet-coated-bolts-supplier\/\">Dacromet coated bolts<\/a> information and the <a href=\"https:\/\/xzfastener.com\/fastener-coating-guide-zinc-hdg-dacromet-ptfe-and-more\/\">fastener coating guide<\/a> before confirming the specification.<\/p>\n        <p>Surface finish should be selected with the whole assembly in mind. A flange bolt may contact painted steel, galvanized steel, aluminum, or another coated component.
