ASTM F1554 Specifications
The specification for ASTM F1554 covers straight and bent, headed and headless, carbon, carbon boron, alloy, or high-strength low alloy steel anchor bolts (also known as anchor rods). The anchor bolts are furnished in three strength grades, and in the sizes specified below
Mechanical Requirements
| Grade | Marking | Size inches | Tensile Strength, ksi (MPa) | Yield Strength, min,ksi (MPa) |
| 36 |  |
1⁄4 – 4 | 58 – 80(400-558) | 36(248) |
| 55 |  |
1⁄4 – 4 | 75 – 95(517-655) | 55(380) |
| 105 |  |
1⁄4 – 3 | 125 – 150(862-1034) | 105(724) |
Grades
| F1554 Grade 36 | Low carbon, 36 ksi yield steel anchor bolts |
| F1554 Grade 55 | High strength, low alloy, 55 ksi yield steel anchor bolts |
| F1554 Grade 105 | Alloy, heat treated, high strength 105 ksi yield steel anchor bolts |
** When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option.
Threading: Threads shall be rolled, cut or ground at the option of the manufacturer, unless otherwise specified
