Asme A307

ASME A307 (often referred to interchangeably with ASTM A307) is a fundamental specification for carbon steel bolts, studs, and threaded rods. The market for these fasteners is currently transitioning toward higher traceability and sustainable manufacturing practices, with a steady growth forecast through 2026.

Product Insights & Technical Overview

The A307 specification is divided into three primary grades, each serving distinct industrial roles:

* Grade A: The "everyday" bolt used for general construction and light structural applications. These are characterized by a minimum tensile strength of 60 ksi. PortlandboltThreadlineproducts

* Grade B: Specifically engineered for piping systems, particularly those with cast iron flanges. They feature a tensile range of 60–100 ksi to provide a consistent seal without overstressing flanges. AftfastenersPortlandbolt

* Grade C (Now ASTM F1554 Grade 36): Historically used for nonheaded anchor bolts and structural anchorage. While officially replaced in standard updates, it remains a common legacy specification in B2B sourcing. FerroboltPortlandbolt
