ASTM F – 18 Standard Specification for Anchor Bolts, Steel, 36, 55, and ksi Yield Strength
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. The specification also covers all-thread rod for use in anchoring to concrete. The purchaser can specify supplemental requirement S1 which requires weldability through chemical composition restrictions and by a carbon equivalency formula.
Washers are detailed in 6. Contrary to popular belief, not all grade 55 material is weldable. Color coding f1554 the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field. In the latest installment of our Threaded series, we discuss materials used to make threaded rod and which work best for certain applications. In the latest installment of our Threaded series, we discuss threaded rod finishes and identify which work 555 for certain applications.
Stamping of F bolts with manufacturer’s identification is a supplemental requirement S2 Color coding is required unless the grade is stamped in accordance with supplemental requirement S3. 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.
Link to Active This link will always route to the current Active version of the standard. The anchor qstm shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. Overview 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 aztm steel 36 ksi.
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 t1554 This field should be left blank. On the other hand, B7 is heat treated, increasing strength but rendering the wstm more brittle.
Your email address will not be published. For example, common uses are in chemical and petroleum facilities. Grade 55 round bar is not commonly available through local warehouses. This specification covers the chemical, mechanical, and dimensional requirements, and associated test methods for straight and bent, headed adtm headless anchor bolts also known as anchor rods made of carbon, carbon boron, alloy, or high-strength f15554 steel and having specified yield strengths.
The ASTM F specification was introduced in and covers anchor bolts designed to anchor structural supports to concrete foundations.
We offer a wide selection of materials, finishes, and sizes of Figure U-Bolts. They are both heat treated parts with near identical mechanical and chemical requirements. Though relevant for many construction applications and certainly more br than B7, Grade 55 is still a specialty steel that few manufacturers or distributors supply. Work Item s – proposed revisions of this standard.
F1554 Grade 55
ggr 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. Material Substitution 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 Instead of the standard color coding of yellow spray ff1554 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.
Galvanizing F grade 55 anchor bolts can be provided in either a black or galvanized condition. The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt. F anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts.
File upload If you have a drawing or photo of your custom fr, please upload here. If weldability is required, supplementary requirement S1 must be specified.
Materials In the latest installment of our Threaded series, …. Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding. B7 is f11554 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.
Asym 55 is more elastic and available at a lower cost, rendering it more applicable for general construction needs, while B7 is heat treated and contains alloys that make it more suitable for corrosive environments. It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4.
If the application allows for a straight bolt, then B7 can be aatm as a substitute for F Grade Weldable version of the Grade 55 specification. All of the grade 55 round bar that Portland Bolt stocks will meet the S1 weldability requirements. This abstract is a brief summary of the referenced standard.

Historical Version s – view previous versions of standard. When Grade 36 is specified, a weldable Grade 55 may be furnished at the supplier’s option. Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability.
