Can F1554 Grade 105 Anchor Bolts Be Made Above 3” Diameter?

ASTM specifies the diameter range for F1554 grade 105 anchor bolts as ½” through 3”. What are the options for anchor bolts larger than 3” diameter of similar strength?

Because the diameter range is clearly defined as ½” through 3” in the F1554 specification, an anchor bolt larger than 3” diameter can’t be certified to F1554 grade 105. However, there are some other ASTM specifications that may be viable alternatives for diameters outside the parameters of F1554 grade 105.

The table below shows two ASTM specifications (A354 Grade BC and A193 Grade B7) with very similar minimum yield and tensile strength requirements to F1554 Grade 105, and another specification (A354 Grade BD), with higher yield and tensile strength requirements.

If F1554 Grade 105 anchor bolts larger than 3” diameter are specified on your project, consult the Engineer of Record for an appropriate ASTM specification.

ASTM Grade / Diameter Range Yield Strength Min (KSI) Tensile Strength Min (KSI)
F1554 Grade 105  12“- 3” 105 125 (150 max)
A354 Grade BC    14” – 212 109 125
A193 Grade B7    14” – 212 105 125
A354 Grade BD    14” – 212 130 150
ASTM Grade / Diameter Range Yield Strength Min (KSI) Tensile Strength Min (KSI)
A354 Grade BC    258“- 4” 94 115
A193 Grade B7    258“- 4” 95 115
A354 Grade BD    258“- 4” 115 140
