The specification for ASTM F covers straight and bent, headed and headless, carbon, F Grade 36, Low carbon, 36 ksi yield steel anchor bolts.

There used to be an A grade C specification covering anchor bolts, but it was eliminated in and subsequently replaced by F grade Can you please provide the Torque Value required to tighten this anchor bolts? Deepak- Apologies, but we are not familiar enough with Indian standards to know what the equivalent would be.
The bottom line is that these anchor bolts that were supplied are missing data that is required to certify them to F grade I been in the business for 40 years and i can make history on this project. The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length.
When Grade 36 is specified, a weldable Grade 55 may adtm furnished at the supplier’s option.
It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section graee. 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 question was submitted by a Port Authority on the East Coast.
Dan- If your local fastener gdade are unable to provide this material, we would be happy to quote you on your needs. Pearce- Yes, AC bolts are also weldable. As it turns out, they did not. This raised the question what type material is the rods. Leave a Reply Cancel reply Your email address will not be published.
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. Many companies attempt to substitute A anchor bolts for F grade 36 anchor bolts as has occurred in this case.
Steel City Bolt – ASTM F Specification
Most likely, the test ggade not performed since this is only a test of F and not a test required of A Thank aatm for your help To address your first question: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Tensile, yield, and elongation are all good, but the reduction of area requirement has not been met. Sorry for being late to send you a clear copy of the Mill certification.
Washers are detailed in 6. 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.
A307 Grade 36 vs F1554 Grade 36
The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. F Grades F Grade 36 Low carbon, 36 ksi yield steel anchor bolts F Grade 55 High strength, low alloy, 55 ksi yield steel anchor bolts F Grade Alloy, heat treated, high strength ksi yield steel anchor bolts. Im not a salty veteran but ive had an issue with the architect rejecting my anchor bolt submittal.
F anchor bolts can take the form of either headed bolts, straight rods, or bent 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. Just to refresh your memory: This is really good information for the people who wants to get quick information. ASTM does not give any warranty express or implied or make any representation that the contents of gade abstract are accurate, complete or up to date.

F1554 Grade 36
References to anchor bolts in this standard do not necessarily exclude d1554 rod. Link to Active This link will always route to the current Active version of the standard. Weldable version of the Grade 55 specification. Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise.
Both A and F grade 36 bolts are frequently manufactured using A36 steel. I was able to f1545 that the was replaced years ago with the and that ipso facto, the was in fact a subsection of the non headed spec. ASTM A is a specification that covers mild steel bolts. Therefore, based on the test reports that accompanied the axtm that were supplied, these anchor bolts do not meet all of the requirements of F grade The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods.
ASTM A36 is a steel grade, not a bolt specification. For the anchor bolts in question, either this test was never performed or the data was never recorded on the test report. 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.
The anchor bolts are zstm 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. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements.
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. Leave this field empty. This abstract is a brief summary of the referenced standard.
