A354 ANSI Carbon Steel HDG 1 Inch All Thread Rod
ASTM A354 covers the chemical and mechanical requirements of quenched and tempered alloy steel bolts, studs, and other externally threaded fasteners 4” and under in diameter. Two strength levels, grades BC and BD are summarized below. This specification is unrestricted in its configuration and can be a headed bolt, bent bolt, or threaded rod.

| BD | Grade BD bolts are higher in strength than grade BC, and equal in strength to ASTM F3125 grade A490 bolts. Unlike A490 however, the A354 standard is unrestricted in its configuration. Also, since A490 bolts are for structural use and do not exceed 1-1/2” in diameter, A354 grade BD should be considered for anchor bolts, threaded rods, other styles of headed bolts, and bolts larger than 1-1/2” diameter where similar mechanical properties are desired. A354 grade BD does not require a magnetic particle test like A490, except when called out as a supplemental requirement. |
|---|---|
| BC | Lower in strength than BD. Should be considered in lieu of F3125 grade A325 bolts when configuration and size conflicts occur with A325 as described above for grade BD and A490 bolts./td> |

Specification
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.
