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.

A307 Grade 36 vs F1554 Grade 36

Anchor bolts were supplied by another company claiming they met or exceeded the requirements of F grade As it turns out, they did not. Sorry for being late to send you a clear copy of the Mill certification.

Just to refresh your memory: Attached is a clearer copy for the Mill Certification. Are we missing any information in the mill certification for the F — see attached — is f1545 provided information in the mill certification can be passed as ASTM F? ASTM A36 is a steel grade, not a bolt specification.

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

Both A and F grade 36 bolts are frequently manufactured using A36 steel. ASTM A is a specification that covers mild steel bolts.

F Grade 36 – F Anchor Bolts

There are two grades within the ASTM specification. A grade A covers bolts for general applications, while A grade B covers heavy hex bolts and studs for cast iron flanges. There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade Both A grade C when it existed and F 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, F grade 36 requires additional testing reduction of area that A grade C did not require. Asttm the anchor bolts in question, either this test was never performed or the data was never recorded on the test report.

F1554 Grade 36

Most likely, the test was not performed since grwde is only a test of F and not a test required of A 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 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 F grade Tensile, yield, and elongation are all good, but the reduction of area requirement has not been met. Many f155 attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred grsde this case.

The bottom line is that these anchor bolts that were supplied are missing data that gtade required to certify them to F grade Deepak- Apologies, but we are not familiar enough with Indian standards to know what the equivalent would be. Thank you for any help you can offer! Dan- If your local fastener distributors are unable to provide g1554 material, we would be happy to quote you on your needs.

Can you please provide the Torque Value required to tighten this anchor bolts? Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise.

This was an extremely helpful article for me. Im not a salty veteran but ive had an issue with the architect rejecting my anchor bolt submittal. I supplied an ASTM grade 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.

Fantastic trump card for me. I f154 in the business for 40 years and i can make history on this project.

But this is one of the problems we have the structural engineer graade pretty tough on the fabricator make sure he followed all the specifications to the Tee. Several of the structural steel column baseplate anchor bolts did not line up and additional anchor bolts had to be added to the structure.

The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods. This raised the question what type material is the rods.

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. Your email address will not be published.

Leave this field empty. Hi Greg, Sorry for being late to send you a clear copy of the Mill certification.

Thank you for your help To address your first question: Ricardo- El acero A36 se utiliza normalmente para fabricar pernos de anclaje F grado Pearce- Yes, AC bolts are also weldable. Thank you very much. This is really good information for the people who wants to get quick information. Leave a Reply Cancel reply Your email address will not be published.
