Samuel Steels stands as a trusted name in Abuja’s construction and industrial supply sector, renowned for providing robust and reliable fastening solutions. We specialize in the supply of high-tensile Alloy Steel Grade 10.9 Bolts, engineered to meet the most demanding projects across Nigeria. Our commitment is to support the nation’s growing infrastructure with products that guarantee integrity and safety, ensuring every structure we contribute to is built on a foundation of unwavering strength and quality you can depend on.
Crafted from a specific alloy composition, these bolts are designed for exceptional performance. The steel is enhanced with elements like chromium and molybdenum, which work together to create a superior strength-to-weight ratio. This results in a fastener that boasts a minimum tensile strength of 1000 MPa and a yield strength of 900 MPa, offering remarkable resistance to shock, vibration, and fatigue, making them a cornerstone for critical applications where failure is not an option.
