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.

Pearce- Yes, AC bolts are also weldable. This abstract is a brief summary of the referenced standard. Sorry for being late to send you a clear copy of the Mill certification. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were. This is really good information for the people who wants to get quick information. 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 Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications.

The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. Thank you very much.

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. 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.


F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area. Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field.

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. The three grades 36, 55, and designate the minimum yield strength ksi of the grdae bolt.

A307 Grade 36 vs F1554 Grade 36

As you can see in the table below, F grade 36 requires additional testing reduction of area that A grade C did not require. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Ricardo- El acero A36 se utiliza normalmente para fabricar pernos de anclaje F grado ASTM A is a specification that covers mild steel bolts.

The bottom line is that these anchor bolts that were supplied are missing data that is required to certify them to F grade Washers are detailed in 6. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements. 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.

Most likely, the test was not performed since this is only a test of F and not a test required of A This question was submitted by a Port Authority on the East Coast.

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.


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

Hi Greg, Sorry for being late to send you a clear copy of the Mill certification. The problem was as the steel inspector i noticed a brade depot sticker on the all threaded rods.

Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding. Fantastic trump card for asgm. 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.

I supplied an ASTM grade It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4. Can you please provide the Torque Value required to tighten this anchor bolts? The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations.

There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently sstm by F grade Work Item s – proposed revisions of this standard. 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. Supplementary requirements shall apply only when specified in the purchase order or contract.

Many companies attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred in this case. 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.
