ASTM A354 Bolts
Quenched & tempered A354 steel bolts, studs and fasteners for structural and heavy-duty use. Atlanta Rod manufactures A354 bolts in-house to meet your project’s specific requirements.
Specifications
The ASTM A354 Bolts specifications covers the chemical and mechanical requirements of quenched and tempered alloy steel bolts, studs, and other externally threaded fasteners 4″ and under in diameter. This specification has no restrictions in its configuration and can be a threaded rod, headed bolt or a bent bolt. The ASTM A354 bolts are not designed to be used in applications where they are tensioned to more than half of their rated tensile strength. In applications requiring more than half the rated tensile strength, a heavy hex head bolt is recommended.
- Grade BC:
- Lower in strength than grade BD.
- Grade BD:
- Higher in strength than A354 grade BC and equal in strength to ASTM A490 bolts. The A354 BD specification has no restrictions on configuration.
- A354 BD should be considered for anchor bolts, threaded rods, other styles of headed bolts, and bolts larger than 1-1/2″ diameter where properties similar to A490 are needed.
- A354 grade BD does not require a magnetic particle test.
