There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy aetm in the field. F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. It provides for anchor bolts in three strength grades, two thread classes, and f11554 the diameters specified in Section 4. Deepak- Apologies, but we are not familiar enough with Indian standards to know what the equivalent would be. Your email address will not be published.

For the anchor bolts in question, either this test was never performed or the data was never recorded on the test report. Leave this field empty.

F Grade 36 – F Anchor Bolts

Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications. Thank you for your help To address sstm first question: Stamping of F bolts with manufacturer’s identification is a supplemental requirement S2 Color coding is required unless the grade is stamped in accordance with supplemental requirement S3.

The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, f154 no one specimen falling below 12ft-lbs. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area. The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis. Many companies attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred in this case.


This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars.

The anchor bolts shall also meet specified 63 for nominal size, body diameter, bend section, length, bend angle, and coated length. The ASTM F specification was aastm in and covers anchor bolts designed to anchor structural supports to concrete foundations. This question was submitted by a Port Authority on the East Coast.

Dan- If your local fastener distributors are unable to provide this material, we would be happy to quote you on your needs.

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 F grade Just to refresh your memory: Anchor bolts were supplied by another company claiming they met or exceeded the requirements of F grade No other units of measurement are included in this standard.

The anchor bolts are furnished in three strength grades, two thread classes, and various sizes, and are intended for anchoring structural supports to concrete foundations such as building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications. Supplementary requirements shall apply only when specified in the purchase order or contract. This raised the question what type material is the rods.

ASTM F1554

T1554 chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability. But this is one of the problems we have the structural engineer was pretty tough on the fabricator make sure he followed all the specifications to the Tee.

I was able to explain that the was replaced years ago with the and that ipso facto, the was in fact a subsection of the non headed spec. F Grades F Grade 36 Low carbon, 36 ksi yield steel anchor bolts F Grade 55 High f1545, low alloy, 55 ksi yield steel anchor bolts F Grade Alloy, heat treated, high strength ksi yield steel anchor bolts.

When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.


It covers the raw material in this case steel round bar that is used to manufacture the bolts.

Are we missing any information in the mill certification for the F — see attached — is the provided information in the mill certification can be passed as ASTM F? Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise. Washers are detailed in 6. There are two grades within the ASTM specification. The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods.

Link to Active This link will always route to the current Active version of the standard. ASTM A36 is a steel grade, not a bolt specification. When S1 is not specified, the Grade 55 material may or may not be weldable. This specification covers the chemical, mechanical, and dimensional requirements, and associated test methods for straight and bent, headed and headless anchor bolts also known as anchor rods made of carbon, carbon boron, alloy, or high-strength low-alloy steel and having specified yield strengths.

Historical Version s – view previous versions of standard.

A307 Grade 36 vs F1554 Grade 36

A grade A covers bolts for general applications, while A grade B covers heavy hex bolts and studs for cast iron flanges. Thank you for any help you can offer!

The specification also covers all-thread rod for use in anchoring to concrete. As you can see in the table below, F grade 36 requires additional testing reduction of area that A grade C did not require.

The only way to be absolutely certain would be to send one piece to a test lab and have them run a mechanical and chemical analysis on it. Weldable version of the Grade 55 specification. The three grades 36, 55, and designate the minimum yield strength ksi of the gfade bolt.

A grade DH or A grade 2H should be substituted. Both A and F grade 36 bolts are frequently manufactured using A36 steel.
