F1554 Grade 36
References to anchor bolts in this standard do not necessarily exclude all-thread rod. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements. As it turns out, they did not. It covers the raw material in this case steel round bar that is used to manufacture the bolts. There is a very good chance that the bolts would meet this requirement if they were tested, but they never were.
Thank you very much. Thank you for any help you can offer!
ASTM A is a specification that covers mild steel bolts. This is really good information for the people who wants to get quick information. This question was submitted by a Port Authority on the East Coast. I been in the business for 40 years and i can make history on this project. 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.
But this is f154 of the problems we have the structural engineer was pretty gradr on the fabricator make sure he followed all the specifications to the Tee. Your email address will not be published. F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts.
There are two grades within the ASTM specification. 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.
Just to refresh your memory: Can you please provide the Torque Value required to tighten this anchor bolts? Several of the structural steel column baseplate anchor bolts did not line up and additional anchor bolts had to be added to the structure. The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods. When Grade 36 is specified, a weldable Grade 55 may ast furnished at the supplier’s option.
Dan- If your local fastener distributors are unable to provide this material, we would be happy to quote you on your needs. Anchor bolts were supplied by another company claiming they met or asgm the requirements of F grade Link to Active This link gradde always route to the current Active version of the standard. Attached is a clearer copy for the Mill Certification.
The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. For the anchor bolts in question, either this test was never performed or the data was never recorded on the test report. The only way to satm absolutely certain would be to send one piece to a test lab and have them run a mechanical and chemical analysis on it.
Sorry for being late to send you a clear copy of the Mill certification. No other units of measurement are included in this standard.
A Grade 36 vs F Grade 36 – Portland Bolt
Most likely, the test was not performed since this is only a test of F and not a test required of A 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. Thank you for your help To address your first question: There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade Hi Greg, Sorry for being late to send you a clear copy of the Mill certification.
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? 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. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.
As you can see in the table below, F grade 36 requires additional testing reduction of area that A grade C did not require.
