Grade 8 fasteners are high-strength bolts, nuts, and washers made from medium carbon alloy steel, typically heat-treated to provide a tensile strength of 150,000 psi. Available in inch sizes, these fasteners are commonly used in demanding applications that require superior strength and durability. Grade 8 fasteners are typically marked with six radial lines on the head, signifying their high tensile rating.

These fasteners are widely used in industries such as automotive, construction, heavy machinery, and manufacturing, particularly for securing critical components that undergo significant stress. For example, they are commonly used in engine assemblies, suspension systems, structural supports, and other high-load-bearing applications. Due to their excellent strength, they are ideal for fastening parts that experience high vibrations, shear forces, or thermal cycling.

Users of Grade 8 fasteners range from automotive manufacturers and repair shops to construction companies and equipment maintenance teams. Engineers and designers specify these fasteners in projects requiring high mechanical integrity, while DIY enthusiasts and hobbyists may use them for personal vehicle upgrades or machinery repairs. Their robust performance in extreme conditions makes them a go-to choice for projects where failure is not an option. While they are costlier than lower-grade fasteners, their reliability and strength justify the investment for critical applications.
