A307 All Thread Rod, Plated
The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4" through 4" diameter. A307 is an economical low carbon material often manufactured using A36 round bar. Dimensional specifications are governed by ASME B18.31.3. A307 all thread rod is available in zinc plated finish. Zinc plating sacrifices itself, corroding before the base material, offering added corrosion resistance. The all thread rod listed on this page is domestic where specified, melted and manufactured in the USA.
