Commonly used Grade 5 hex cap screws are heavier duty than Grade 2 steel options and are made from medium carbon steel and heat-treated. Grade 5 steel has 120,000 psi tensile strength and meets ASME B18.2.1 dimensional standards and SAE J429 material quality standards. These screws may be used in medium-duty applications. They come in a black oxide finish or may be zinc plated or chrome plated. Zinc plating helps provide durability in wet environments. Chrome plating increases the hardness, durability, and corrosion resistance of screws. * Grainger’s product supplier has certified that products marked “Made in USA” below comply with "Made in USA" requirements in accordance with FTC rules and guidance
