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. References to anchor bolts in this standard do not necessarily exclude all-thread rod. Tr ASTM F grade 55 anchor bolts are manufactured from a modified mild steel that has a higher minimum yield strength 55 ksi than traditional A36 mild steel 36 ksi.
The specification also covers all-thread rod for use in anchoring to concrete.
The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations. 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.
Historical Version s – view previous versions of standard. The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. Be skeptical of fastener distributors and manufacturers with limited manufacturing capabilities who attempt to substitute round bar or even A grade B7 material for F grade Grade 55 round bar is not commonly available through local warehouses.
In addition to standard round be… https: If the application allows for a straight bolt, then B7 can be considered as a substitute for F Grade When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option. Materials In the latest installment of our Threaded series, …. They shall also be tested for their conformance with mechanical properties such as tensile strength, yield strength, elongation, reduction of area, and stress area.
The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt. B7 is an alloy which includes chromium and molybdenum for added strength and corrosion resistance, rendering it suitable for applications that are highly susceptible to corrosion at high temperatures.
ASTM F1554 Grade 55 vs ASTM A193 B7
A grade DH or A grade 2H should be substituted. This abstract is a brief summary of the referenced standard. Please describe your threaded product needs with as much detail as possible and we will consult you on what will most benefit your objectives.
Weldable version aastm the Grade 55 specification. 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. If S1 is not specified by the purchaser, the Grade 55 material may or may not be weldable.
Grade 55 is more elastic and available at a lower cost, rendering it more applicable for general aatm needs, while B7 is heat treated and contains alloys that make it more suitable for corrosive environments.
This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars.
Steel City Bolt – ASTM F Specification
The following supplemental requirements apply to F Grade All of the grade 55 round bar that Portland Bolt stocks will meet the S1 weldability requirements.
This specification was widely used in the light pole and traffic signal industry long before the ASTM F specification was introduced in and was commonly referred to as A36M We are a prime U. In the latest installment of our Threaded series, we discuss materials used to make threaded rod and which work best for certain applications.
In this series, we will be covering four common topics to help you build the foundation you need to better understand the threaded fastener industry. The minimum Charpy V-notch energy requirement ff1554 an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. Portland Bolt buys mill runs of round bar and stocks this material for immediate processing. Galvanizing F grade 55 anchor bolts can be provided in either a black or galvanized condition.
The anchor bolts shall also meet specified values for nominal size, xstm diameter, bend section, length, bend angle, and coated length. Supplementary requirements shall apply only when specified in the purchase order or contract.
F Grade 55 – F Anchor Bolts
We offer a wide selection of materials, finishes, and sizes of Figure U-Bolts. On r1554 other hand, B7 is heat treated, increasing strength but rendering the material more brittle. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements. They are both heat treated parts with near identical mechanical and chemical requirements.

For example, common uses are in chemical and petroleum facilities. Instead of the standard color coding of yellow spray paint to indicate Grade 55, supplemental requirement S3 can be specified by the purchaser to have a permanent grade identification on the end of the anchor bolt that projects from the concrete.
