Bolts, rods and studs: BC and BD grades
A354 covers quenched and tempered alloy-steel threaded fasteners with specified geometry. It supports industrial requirements and configurations needing a specification other than F3125 structural bolts.
Reference mechanical properties · inch series
| Grade | Diameter | Tensile · ksi | Yield min. · ksi | HRC |
|---|---|---|---|---|
| BC | ¼–2½″ | ≥125 | 109 | 26–36 |
| BC | 2¾–4″ | ≥115 | 99 | 22–33 |
| BD | ¼–4″ | 150–173 | 130 | 33–38 |
Similar strength does not establish equivalence with A325 or A490. Specify geometry, supplementary testing, coating and mating components.
Specification-led dimensions and configuration
Specify grade, diameter, length, thread and configuration for a supply assessment. Dedicated production is subject to minimum quantity and technical feasibility.
