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.

Eduardo- The AISC guidelines say that snug tight is all gradw is required for anchor bolts, unless the project engineer says otherwise. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt.

Just to refresh your memory: There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4.

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

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.

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? 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. 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. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were.


ASTM A is a specification that covers mild steel bolts. ASTM A36 is a steel grade, not a bolt specification. This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars.

Im not a salty veteran but ive had an issue with the architect rejecting my anchor bolt submittal. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs.

F1554 Grade 36

It is informational only and not an official part of the standard; the full text of the standard 63 must be referred to for its use and application. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements.

When S1 is not specified, the Grade 55 material may or may not be weldable. A grade DH or A brade 2H should be substituted. Several of the structural steel column baseplate anchor bolts did not line up and additional anchor bolts had to be added to the structure. Pearce- Yes, AC bolts are also weldable. Stamping of F bolts with manufacturer’s identification is a supplemental requirement S2 Color coding gradr required unless the grade is stamped in accordance with supplemental requirement S3.

Thank you for your help To address your first question: Attached is a clearer copy for the Mill Certification. I been in the business for 40 years grad i can make history on this project. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.

ASTM F – 18 Standard Specification for Anchor Bolts, Steel, 36, 55, and ksi Yield Strength

Fantastic trump card for me. Anchor bolts were supplied by another company claiming they met or exceeded the requirements of F grade Your email address will not be published.

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. Many companies attempt to substitute A anchor bolts for F15554 grade 36 anchor bolts as has occurred in this case. There are two grades within the ASTM specification. For the anchor bolts in question, either this test was never performed or the data was never recorded on the test report. I supplied an ASTM grade Hi Greg, Sorry for being late to send you a clear copy of the Mill certification.


Thank you for any help you can offer!

ASTM F1554

Tensile, yield, and elongation are all good, but the reduction of area requirement has not been met. 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. When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option. Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field.

F Grade 36 – F Anchor Bolts

Therefore, based on the test reports that accompanied the bolts that were supplied, these anchor bolts do not meet all of rgade requirements of F grade This is really good information for the people who wants to get quick information. Can you please provide the Torque Value required to tighten this anchor asttm The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length.

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. Washers are detailed in 6. References to anchor bolts in this standard do not necessarily exclude all-thread rod.
