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.

As you can ff1554 in the table below, F grade 36 requires additional testing reduction of area that A grade C did not require. A grade A covers bolts for general applications, while A grade B covers heavy hex bolts and studs for cast iron flanges.
ASTM A is a specification that covers mild steel bolts. The specification also covers all-thread rod for use in anchoring to concrete. This abstract is a brief summary of the referenced standard.
A307 Grade 36 vs F1554 Grade 36
The bottom line is that these anchor bolts that were supplied are missing data that is required to certify them to F grade Hi Greg, Sorry for being late to send you a clear copy of the Mill certification. Just to refresh your memory: F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications.
This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars.
3 Work Item s – proposed revisions of this standard. 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. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were.
The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations.
Leave this field empty. Several of the structural steel column baseplate anchor bolts did not line up and additional anchor bolts had to be added to the structure.
Thank you for any help you can offer! 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. 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?
Im not a salty veteran but ive had an issue with the architect rejecting my anchor bolt submittal. The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods.
Steel City Bolt – ASTM F Specification
It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4. There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade Pearce- Yes, AC bolts are also weldable. Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field.
Can you please provide the Torque Value required to tighten this anchor bolts? Deepak- Apologies, but we are not 1f554 enough with Indian standards to know what the equivalent would be.
Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability. Leave a Reply Cancel reply Your email address will not be published.
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 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. Fantastic trump card for me. Many companies attempt to asrm A g1554 bolts for F grade 36 anchor bolts as has occurred in this case.
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.
