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.

The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations. A grade A covers bolts for general applications, while A atm B covers heavy hex bolts and studs for cast iron flanges. Thank you for grxde help you can offer! As it turns out, they did not.

Historical Version s – view previous wstm of standard. 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. 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 Applications for F anchor bolts include columns in structural steel framed buildings, traffic signal and street lighting poles, and overhead highway sign structures to name just a few.

ASTM A is a specification that covers mild steel bolts.

Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding. This abstract is a brief summary of the referenced standard. The specification also covers all-thread rod for use in anchoring to concrete.

References to anchor bolts in this standard do not necessarily exclude all-thread rod. 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.

Many companies attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred in this case. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.


There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade Dan- If your local fastener distributors are unable to provide this material, we would be happy to quote you on your needs.

Im not a salty veteran but ive had an issue with the architect rejecting my anchor bolt submittal. The bottom line is that these anchor bolts that were supplied are missing data that is required to certify them to F grade 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 Anchor bolts were supplied by another company claiming they met or exceeded the requirements of F grade 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 manufacturer and grade marking is allowed under the S2 supplementary requirements. Tensile, yield, and elongation are all good, but the reduction of area requirement has not been met.

ASTM F1554

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. 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.

A grade DH or A grade 2H should be substituted. Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise. Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications. 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.


The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt.

F1554 Grade 36

Sorry for being late to send you a clear copy of the Mill certification. ASTM A36 is a steel grade, not a bolt specification. When S1 is not specified, the D1554 55 material may or may not be weldable.

Leave this field empty. Just to refresh your memory: I supplied an ASTM grade It is informational only and not an official part of the standard; f154 full text of the standard itself must be referred to for its use and application.

This is really good information for the people who wants to get quick information. No other units of measurement are included in this standard. Fantastic trump card for me. I been in the business for 40 ast, and i can make history on this project.

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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but grads not provided as part of the standard.

Washers are detailed in 6. 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. It covers the raw material in this case steel round bar that is used to manufacture the bolts. Thank you very much.

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