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.

Governing StandardsGrade A307A

ASTM A307 Covers the mechanical and material requirements for inch series fasteners in diameters from 1/4″ through 4″, made of carbon steel having a minimum tensile strength of 60,000 psi.
ASME B18.31.3 Covers the general and dimensional data for inch series threaded rods.
ASME B1.1 UNC & UNF Class 2A Specifies the thread form, series, class, allowance, tolerance, and designation for unified screw threads.
