Nestled in the bustling industrial heart of Manama, Ahmer Steel stands as a trusted partner for robust and dependable construction materials. We specialize in providing high-performance Carbon Steel 8.8 Fasteners, a cornerstone for projects demanding unwavering strength. Our commitment is to supply a comprehensive range of bolts, nuts, and washers that meet rigorous standards, ensuring your structures are built with integrity and longevity from the ground up.
The strength of Grade 8.8 fasteners comes from a specific medium carbon steel composition that is quenched and tempered. This carefully controlled heat treatment process gives them a minimum tensile strength of 800 MPa and a yield strength of 640 MPa. This means they offer an excellent balance of toughness and durability, capable of handling significant stress without deforming, making them a reliable choice for a vast array of demanding applications.
