Welcome to Samuel Steels, your trusted partner for industrial strength in Abuja, Nigeria. We specialize in supplying high-quality Alloy Steel Grade 8.8 fasteners, providing the essential nuts, bolts, and screws that form the backbone of robust construction and manufacturing projects across the region. Our commitment is to deliver reliability and durability, ensuring every connection we help make is built to last and perform under pressure, right here in the heart of the nation’s capital.
These fasteners are crafted from a medium carbon steel alloy, often including boron, which is quenched and tempered to achieve its notable strength. This specific heat treatment process gives Grade 8.8 its excellent balance, offering a minimum tensile strength of 800 MPa and a yield strength of 640 MPa. This means they possess a great deal of toughness and can withstand significant stress before deforming, making them a dependable choice for a wide array of demanding applications.
