ASTM A307 carbon steel bolts, studs, and threaded Scope

ASTM A307 is the standard specification for carbon steel bolts, studs, and threaded rods of 60000 PSI tensile strength in sizes from ¼ inch to 4 inches in diameter. A307 bolts from Glaser and Associates are available in two grades, A and B, offering different mechanical and chemical properties for specific applications.

These bolts are designed, manufactured and tested to comply with the standards set by ASTM A307 for chemical composition, hardness, tensile strength, yield point, elongation, and dimensional accuracy.

ASTM A307 carbon steel Grades Fasteners

• Grade A – headed bolts, threaded rods and bent bolts with a minimum tensile strength of 60 ksi for a wide range of general-purpose applications.
• Grade B  - heavy hex bolts and studs with a tensile strength of 60 to 100 ksi for flanged joints in piping systems with cast iron flanges.

The properties tables below provide more information on the differences between the grades.

Applications

Anchor bolts from Glaser and Associates provide secure foundations in a wide range of industrial, mechanical and structural applications. They are designed to anchor or support structures and industrial equipment in environments where durability and stability is essential. Common applications include concrete forms, columns, foundations and pads.

For applications that must meet specific engineering requirements, custom-designed headed anchor bolts, anchor rods and bent anchor bolts in specific materials may be more suitable. Please consult our technical department

A307 Grade 36 vs F1554 Grade 36

ASTM A36 is a steel grade, not a bolt specification. It covers the raw material (in this case steel round bar) that is used to manufacture the bolts. A307 and F1554 grade 36 are ASTM specifications covering bolts. Both A307 and F1554 grade 36 bolts are frequently manufactured using A36 steel. ASTM A307 is a specification that covers mild steel bolts. There are two grades within the ASTM specification. A307 grade A covers bolts for general applications, while A307 grade B covers heavy hex bolts and studs for cast iron flanges. There used to be an A307 grade C specification covering anchor bolts, but it was eliminated in 2007 and subsequently replaced by F1554 grade 36.

Both A307 grade C (when it existed) and F1554 grade 36 have chemical and mechanical (strength) requirements that must be met in order to certify the bolts to these specifications. As you can see in the table below, F1554 grade 36 requires additional testing (reduction of area) that A307 grade C did not require.

Mechanical Requirements

Grade	Tensile, ksi	Yield, ksi min	Elongation % min	Reduction of Area % min
A307 grade C	58 - 80	36	23	no requirement
F1554 grade 36	58 - 80	36	23	40

As for the bolts that were supplied…

One of the requirements of F1554 grade 36 is that the Reduction of Area of the steel must exceed 40%. For the anchor bolts in question, either this test was never performed or the data was never recorded on the test report. Most likely, the test was not performed since this is only a test of F1554 and not a test required of A307. Since this value is missing, there is no way to determine whether or not the bolts that were supplied (and are already in the foundation) have enough ductility (as determined by the Reduction of Area test) to meet the requirements of F1554 grade 36. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were. Therefore, based on the test reports that accompanied the bolts that were supplied, these anchor bolts do not meet all of the requirements of F1554 grade 36. Tensile, yield, and elongation are all good, but the reduction of area requirement has not been met.

Many companies attempt to substitute A307 anchor bolts for F1554 grade 36 anchor bolts as has occurred in this case. The bottom line is that these anchor bolts that were supplied are missing data that is required to certify them to F1554 grade 36.
