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.

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, heat treated, high strength ksi yield steel anchor bolts. This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars. Work Item s – proposed atm of this standard.

ASTM F1554

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. Both A and F grade 36 bolts are frequently manufactured using A36 steel. 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 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. This specification covers the chemical, mechanical, and dimensional requirements, and associated test methods for straight and bent, headed and headless anchor bolts also astmm as anchor rods made of carbon, carbon boron, alloy, or high-strength low-alloy steel and having specified yield strengths.

F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt. 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.


There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods. 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 A grade A covers bolts for general applications, while A grade B covers heavy hex bolts and studs for cast iron flanges.

Im not a salty veteran but ive had an issue with gradde architect rejecting my anchor bolt submittal. This astk is a brief summary of the referenced standard. As it turns out, they did not.

A grade DH or A grade 2H should be substituted. F5154 companies attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred in this case. The specification also covers all-thread rod for use in anchoring to concrete.

For the anchor bolts in question, either this test was never performed or the data was never recorded on the test report. 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. ASTM A is a specification that covers mild steel bolts. Just to refresh your memory: ASTM A36 is a steel grade, garde a bolt specification.

Thank you for any help you can offer! Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements. 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? Thank you very much.


Your email address will not be published. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were. 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. Leave this field empty. The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis.

Tensile, yield, and elongation are all good, but the reduction of area requirement has not been met. Dan- If your local fastener distributors are unable to provide this material, we would be happy to quote you on your needs. Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below gradde.

There are two grades within the ASTM specification. The only way to be absolutely certain would axtm to send one piece to a test lab and have them run a mechanical and chemical analysis on it. Such structural supports include building columns, column supports for highway signs, street adtm and traffic signals, steel bearing plates, and similar applications.
