F1554 Grade 55 All Thread Rod

ASTM F1554 Grade 55 all thread rod is a designed strength, low to medium carbon content grade. It has a 55 ksi yield strength which is required by the ASTM F1554 specification for anchor bolt and fastener applications. Dimensional specifications are governed by ASME B18.31.3. ASTM F1554 covers the mechanical and material properties of steel anchor bolts having a yield strength of 36, 55 and 105 ksi. These applications often include F1554 Grade 55 rods used as all thread anchors or as part of an F1554 anchor bolt assembly. Anchor bolts are used to anchor a structure to a concrete foundation. They are embedded in concrete and have a threaded portion which projects from the concrete. The embedded portion of the anchor bolt creates resistance to prevent the anchor from pulling out of the concrete when a load is applied. Some projects may also compare this material to grade 5 threaded rod, depending on strength needs and engineering requirements.
