Overview. ASTM F grade 36 anchor bolts are manufactured from A36, low carbon steel. This is your standard, run-of-the-mill bolt grade covering anchor. The specification for ASTM F covers straight and bent, headed and headless, carbon, F Grade 36, Low carbon, 36 ksi yield steel anchor bolts. The ASTM F specification covers anchor bolts designed to anchor structural supports to concrete foundations; F comes in three grades 36, 55, and.

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.

Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise. Deepak- Apologies, but we are not familiar enough with Indian standards to know what the equivalent would be.

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.

A grade A covers bolts for general applications, while A grade B covers heavy hex bolts and studs for cast iron flanges. This question was submitted by a Port Authority on the East Coast. Attached is a clearer grads for the Mill Certification. Link to Active This link will always route to the current Active version of the standard.

ASTM F – Portland Bolt

The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements.

Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability.

The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. This was an extremely helpful article for me. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were.


A grade DH or A grade 2H should be substituted. Just to refresh your memory: I supplied an ASTM grade Leave a Reply Cancel reply Your email address will not be published. But this is one of the problems we have the structural engineer was pretty tough on the fabricator graed sure he followed all the specifications to the Tee. Historical Version s – view previous versions of standard. When S1 is not specified, the Grade 55 material may or may not be weldable.

The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis. Thank you very much. Weldable version g1554 the Grade 55 specification.

Work Item s – proposed revisions of this standard.

As you can see in the table below, F grade 36 requires additional testing reduction of area that A grade C did not require.

Both A and F grade 36 bolts are frequently manufactured using A36 steel.

It is informational only and not an official part of the standard; the full text gade the standard itself must be referred to for its use and application. ASTM A is a specification that covers mild steel bolts. The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations. No other aatm of measurement are included in this standard.

The specification also covers all-thread rod for use in anchoring to concrete. 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?

Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field. F Grades F Grade 36 Low carbon, 36 ksi yield steel anchor bolts F Grade 55 High strength, low alloy, 55 ksi yield steel anchor bolts F Grade Alloy, f155 treated, high strength ksi yield steel anchor bolts.


Pearce- Yes, AC bolts are also weldable. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt. References to anchor bolts in this standard do not necessarily exclude all-thread rod. Fantastic trump card for me. Therefore, based on the test reports that accompanied the bolts that were supplied, these anchor bolts do not meet all of the requirements of F grade Many companies attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred in this case.

I been in the business for 40 years and i 336 make history on this project. Anchor bolts were supplied by another company claiming they met or exceeded the requirements of F grade Thank you for any help you can offer! Ast of F bolts with manufacturer’s identification is a supplemental requirement S2 Color coding is required gtade the grade is stamped in accordance with supplemental requirement S3.

F1554 Grade 36

There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade It covers the raw material in this case steel round bar that is used to manufacture the bolts.

Most likely, the test was not performed since this is only a test of F and not a test required of A There are two grades within the ASTM specification. This abstract is a brief summary of the referenced 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.

Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding. ASTM A36 is a steel grade, not a bolt specification.
