This is really good information for the people who wants to get quick information. Thank you very much. Historical Version s – view previous versions of standard. Thank you for your help To address your first question: This raised the question what type material is the rods.
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. 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.
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. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.
This abstract is a brief summary of the referenced standard. The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations. The bolts shall adhere to specified elemental chemical compositions as examined by heat and product analysis.
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. Your email address will not be published.
Such structural supports include building columns, column supports for highway signs, street lighting and traffic signals, steel bearing plates, and similar applications.
Hi Greg, Sorry for being late to send you a clear copy of the Mill certification. Can you please provide the Torque Value required to tighten this anchor bolts?
F1554 Grade 36
Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise. 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 problem was as the steel inspector i noticed a home depot sticker on the all threaded rods. 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. As you can see in the table below, F grade 36 requires additional testing reduction of area that A grade C did not require.
Work Item s – proposed revisions of this standard. This was an extremely helpful article for me.
A307 Grade 36 vs F1554 Grade 36
The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. A grade A covers bolts for general applications, while A grade B covers heavy hex bolts and studs for cast iron flanges. The specification also covers all-thread rod for use in anchoring to concrete.
Many companies attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred in this case. Just to refresh your memory: Therefore, based on the test reports that accompanied the bolts that were supplied, these anchor bolts do not meet all of the requirements of F grade Permanent manufacturer and grade marking is allowed under the S2 supplementary f11554. Fantastic trump card for me.
A Grade 36 vs F Grade 36 – Portland Bolt
Tensile, yield, and elongation gradf all good, but the reduction of area requirement has not been met. Im not a salty veteran but ive had an issue with the architect rejecting my anchor bolt submittal.
Both A and F grade 36 bolts are frequently manufactured using A36 steel. There is a very good chance that the bolts would meet d1554 requirement if they were tested, but they never were.
Supplementary requirements shall apply only when specified in the purchase order or contract. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs.
