1️⃣ General machinery assembly. 2️⃣ Wood construction (tensionless connections). 3️⃣ Standard threaded rod (all-thread).

: Historically used for unheaded ground bolts, this grade was replaced in 2007 by the ASTM F1554 Grade 36 specification, though you may still see it referenced in older documentation. Key Technical Specifications

A307 covers carbon steel bolts, studs, and threaded rod intended for general applications. Unlike high-strength bolts, A307 is designed for lower tensile strength requirements, maxing out at 60,000 PSI.

| Grade | Common Use | Key Feature | | :--- | :--- | :--- | | | Wood construction, machinery, shelf brackets. | General purpose. Low cost. | | Grade B | Pipe flanges, pressure vessels. | Higher temperature resistance. | | Grade C | Note: Previously used for anchor bolts, but this grade was withdrawn in 2007. If you see specs calling for Grade C, update to F1554 Grade 36 or 55. |

: While A36 is the raw material (steel bar), ASTM A307 is the fastener specification that describes the finished product once it has been threaded, forged, or bent.

While high-strength bolts (like A325) are for heavy structural loads, A307 is your go-to for general applications.
