Carbon Steel Fasteners – 8.8 / 10.9 / 12.9 / B7/L7
Grades for High-Performance Applications

Carbon steel is a versatile iron alloy with carbon as the primary alloying element. The addition of carbon enhances its strength, hardness and wear resistance, with properties that vary depending on the carbon content. Carbon steel is commonly categorised into low, medium, and high carbon grades, with higher carbon content resulting in increased tensile strength and reduced ductility. For fasteners, grades such as 8.8, 10.9, and 12.9 offer varying strength levels, while B7 and L7 are commonly used in high-pressure and high-temperature applications. Although carbon steel is cost-effective and easy to machine, it is prone to corrosion if not adequately protected, making it crucial to apply appropriate coatings or finishes for environmental resistance. Our carbon steel fasteners are manufactured to precise engineering specifications, ensuring reliable performance in demanding mechanical and structural applications.
