B7 All Thread Rod, Plated
ASTM A193 Grade B7 all thread rod is manufactured from an alloy which includes chromium-molybdenum steel, quenched and tempered, for added strength and corrosion resistance. Dimensional specifications are governed by ASME B18.31.3. Inch series fasteners meeting ASTM A193 Grade B7 specifications are typically used in flange bolting applications. ASTM A193 covers the requirements for high temperature and high pressure bolting. These fasteners are available in yellow zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance.
