Supplementary requirements shall apply only when specified in the purchase order or contract. Can you please provide the Torque Value required to tighten this anchor bolts?

Thank you very much. Leave this field empty. 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 When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option.

Ast, are detailed in 6. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. This abstract is a brief summary of the referenced standard. It covers the raw material in this case steel round bar that is used to manufacture the bolts.

ASTM F – Portland Bolt

Attached is a clearer copy for grqde Mill Certification. Link to Active This link will always route to the current Active version of the standard.

Eduardo- The AISC guidelines say that snug tight is all that is required for anchor bolts, unless the project engineer says otherwise. ASTM A is a specification that covers mild steel bolts. The specification also covers all-thread rod for use in anchoring to concrete. 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 S1 is not specified, the Grade 55 material may or may not be weldable.


A Grade 36 vs F Grade 36 – Portland Bolt

aatm Historical Version s – view previous versions of standard. The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations.

As it turns out, they did not. Ricardo- El acero A36 se utiliza normalmente para fabricar pernos de anclaje F grado The problem was as the steel inspector i noticed a home depot sticker on the all threaded rods.

The bottom line is that grase anchor bolts that were supplied are missing data that is required to certify them to F grade Work Item s – proposed revisions of this standard. Your email address will not be published.

A307 Grade 36 vs F1554 Grade 36

Thank you for any help you can offer! As hrade can see in the table below, F grade 36 requires additional testing reduction of area asm A grade C did not require. Since this value is missing, there is no way to determine whether or not the bolts that were 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 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.

Sorry for being late to send you a clear copy of the Mill certification.


ASTM F1554

There are two grades within the ASTM specification. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area. Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field. Leave a Reply Cancel reply Your email address will not be published. This was an extremely helpful article for me.

Both A and F grade 36 bolts are frequently manufactured using A36 steel. ASTM A36 is a steel grade, not a bolt specification.

I been asm the business for 40 years and i can make history on this project.

References to anchor bolts in this standard do not necessarily exclude all-thread rod. The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. I supplied an ASTM grade This raised the question geade type material is the rods.

Thank you for your help To address your first question: F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. 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.
