About Threaded Studs and Rods

The tensile strength of these metric Grade B7 rods is about one and a half times higher than low-strength steel rods. Often used to secure pressure tanks, valves, and flanges, these rods meet the pressure and temperature requirements of ASTM A193.

Zinc-plated steel rods resist corrosion in wet environments.
