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.

I been in the business for 40 years and i can make history on this project. Im not a salty veteran but ive had an issue with the architect rejecting my anchor bolt submittal.
ASTM F – 18 Standard Specification for Anchor Bolts, Steel, 36, 55, and ksi Yield Strength
Applications for F anchor bolts include columns in structural steel framed buildings, traffic signal and street lighting poles, and overhead highway sign ggrade to name just a few. I supplied an ASTM grade This is really good information for the people who wants to get quick information. Attached is a clearer copy for the Mill Certification. This was an extremely grdae article for me. Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding.
Anchor bolts were supplied by another company claiming they met or exceeded the requirements of F grade They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of gade, and stress area.
Fantastic trump card for me. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were. This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated gradr or studs, and anchor bolts fabricated from deformed bars.
When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option.
Both A and F grade 36 bolts are frequently manufactured using A36 steel. Just to refresh your memory: Hi Greg, Sorry for being late to send you a clear copy of the Mill certification. Tensile, yield, and elongation are all good, but the reduction of area requirement has not been met.
F anchor bolts can take the form of asrm headed bolts, straight rods, or bent anchor bolts. ASTM A36 is a steel grade, not a bolt specification. 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.

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 question was submitted by a Port Authority on the East Coast. Since this value is missing, there is no way to determine whether or not the bolts that grae 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 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 bottom line is that these anchor bolts that were supplied are missing data that is required to certify them to F grade There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy gradf in the field.
A grade A covers bolts for general applications, while A grade B covers heavy hex bolts and studs for cast iron flanges. 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. Can you please provide the Torque Value required to tighten this anchor bolts? The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs.

Your email address will not be published. Thank you for your help To address your first question: This raised the question what type material is the rods. 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.
Weldable version of the Grade 55 specification. This abstract is a brief summary of the referenced standard.
