ASTM F1554 Threaded Rods for Concrete Foundation Anchoring
ASTM F1554 Threaded Rods are straight threaded anchor rods designed to connect structural supports to concrete foundations. Unlike bent anchor bolts such as L-shaped or J-shaped designs, threaded rods use a straight shaft with a threaded section that can be secured with nuts and washers after installation. These anchor rods are commonly used to secure steel columns, structural frames, equipment bases, sign structures, and other supports to concrete foundations. The threaded design allows the exposed end to be adjusted with nuts and washers, while the embedded portion can be installed according to the foundation and anchoring design.
ASTM F1554 covers Grade 36, Grade 55, and Grade 105 anchor bolts and anchor rods, allowing the appropriate strength level to be selected according to the structural requirements. The required diameter, length, thread configuration, material, and anchoring method should be specified according to the project design. We can supply F1554 threaded anchor rods in standard or customer-specified diameters and lengths, with options for full-length threading, partial threading, chamfers, and surface finishes according to the required application.
Specification:
ASTM F1554 Threaded Rods are straight, fully threaded anchor rods designed for securing structural supports to concrete foundations. The ASTM F1554 specification defines the material, chemical composition, mechanical properties, grades, testing, and identification requirements, while ASME B18.31.3 provides dimensional requirements for inch-series threaded rods.
The rods are available in Grades 36, 55, and 105, allowing the appropriate strength level to be selected according to the structural design and anchoring requirements. Thread specifications are based on applicable Unified thread requirements, with UNC commonly used for general applications and other thread series available when specified.

Chemical Composition:
The chemical composition of ASTM F1554 threaded anchor rods is specified according to ASTM F1554-20, with requirements varying by grade. The chemical requirements are established to provide the material characteristics needed for structural anchoring applications. Our F1554 anchor rods are manufactured from carbon steel and supplied according to the specified grade and applicable chemical composition requirements.
The table below summarizes the chemical composition requirements for Grade 36, Grade 55, and Grade 105 based on ASTM F1554-20. Actual material composition is verified through material testing and can be documented in the Mill Test Report (MTR) for applicable orders.
| Chemical Composition | Carbon(max) | Manganese(max) | Phosphorus(max) | Sulfur(max) | Copper min (when specified) |
|---|---|---|---|---|---|
| Grade36(≤3/4“） | 0.28 | 0.05 | 0.06 | 0.18 | |

Mechanical Property:
ASTM F1554-20 specifies the mechanical requirements for Grade 36, Grade 55, and Grade 105 anchor rods, including tensile strength, yield strength, elongation, and reduction of area, where applicable. These requirements define the minimum mechanical performance expected from each grade for structural anchoring applications.
The mechanical property values shown in the table below are based on ASTM F1554-20. Each grade provides a different strength level, allowing the appropriate anchor rod to be selected according to the structural load and engineering requirements.
| Grade | Tension Strength,ksi | Yield Strength(min)ksi | Elongation in 8in(min)% | Elongation in 2in(min)% | Reduction of Area,min% |
|---|---|---|---|---|---|
| Grade36 | 58-80 | 36 | 20 | 23 | 40 |
| Grade55 | 75-90 | 55 | 18 | 21 | 30 |
| Grade105 | 125-150 | 105 | 12 | 12 | 45 |
Application of F1554 Threaded Rod:
Grade 36 Threaded Anchor Rods
ASTM F1554 Grade 36 Threaded Rods are commonly selected for general structural anchoring applications where standard strength is sufficient. They can be used to secure steel columns, base plates, structural frames, sign structures, and other supports to concrete foundations.
Grade 55 Threaded Anchor Rods
ASTM F1554 Grade 55 Threaded Rods provide higher strength than Grade 36 and are suitable for structural applications requiring greater load capacity. Typical applications include steel buildings, industrial structures, structural support systems, bridge components, and heavy-duty foundation connections.
Grade 105 Threaded Anchor Rods
ASTM F1554 Grade 105 Threaded Rods are designed for applications requiring high-strength anchoring performance. They can be used in heavily loaded structural connections, industrial facilities, large steel structures, and other foundation anchoring applications where higher mechanical strength is required.
