Specification

 

The ASTM A307 specification covers carbon steel bolts and studs ranging from 1/4″ through 4″ diameter. This is your everyday, run of the mill bolt specification often manufactured using A36 round bar. There are three grades A, B, and C* which denote tensile strength, configuration, and application. Refer to the Mechanical Properties Chart for the subtle strength differences within each grade.

A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod. They are designed to be used in tension. Threaded rod in bar stock form is often called all-thread.

 

 

All thread rod, commonly referred to as fully threaded rod, redi-rod, continuously threaded rod, TFL rod, and abbreviated ATR is used for general purpose fastening for anything from an anchor bolt to a through bolt. A variety of grades and materials are available.
