About Chrome and Bolt Grades

Chrome bolts and other fasteners are generally grade 2, grade 5 (hardened) or grade 8 (fully hardened) fasteners with a bright mirror-like finish. These fasteners provide sharp looks for a variety of applications.

Chrome plating provides similar corrosion resistance to zinc plating. The main drawback of chrome is its high cost. If more corrosion resistance is required stainless steel may be chrome plated, preventing any corrosion should the chrome be penetrated.

Grade 2 is a standard hardware grade steel. This is the most common grade of steel fastener and is the least expensive. Grade 2 bolts have no head marking (sometimes a manufacturer mark is present).

Grade 5 bolts are case hardened. This means that the outside part of the bolt has been hardened but that the bolt was not heated enough to harden the inside portion. This creates a bolt that is fairly hard but not as brittle as a fully hardened bolt. Grade 5 bolts are the most common bolts found in automotive applications. Grade 5 bolts may have 3 evenly spaced radial lines on the head.

Grade 8 bolts are fully hardened. This means the bolt has been hardened all the way through. This creates a bolt that is very hard but somewhat brittle. Grade 8 bolts are more likely to snap off than bend under extreme loads. Grade 8 bolts are often found in demanding applications such as automotive suspensions. Grade 8 bolts may have 6 evenly spaced radial lines on the head.
