Galvanizing F grade 55 anchor bolts can be provided in either a black or galvanized condition. They are both heat treated parts with near identical mechanical and chemical requirements. F Grades F Grade 36 Low carbon, 36 ksi ge 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.

The minimum Asfm V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. In the latest installment of our Threaded series, we discuss threaded rod finishes and identify which work best for certain applications. Applications for F anchor bolts include columns in structural steel framed buildings, traffic signal and street f154 poles, and overhead highway sign structures to name just satm few.
Input Your Industry required. We offer a wide selection of materials, finishes, and sizes of Figure U-Bolts. If the application allows for a straight bolt, then B7 can be considered as a substitute for F Grade The three grades 36, 55, and designate the minimum yield strength ksi of the anchor bolt.
The minimum Charpy V-notch energy requirement is an average of 15ft-lbs for three specimens, with no one specimen falling below 12ft-lbs. It provides for anchor bolts in three strength grades, two thread classes, and in the diameters specified in Section 4.
ASTM F1554 Grade 55 vs ASTM A193 B7
Grade 55 round bar is not commonly available through local warehouses. Weldable version of the Grade 55 specification. Link to Active This link will always route to the current Active version of the standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
This specification, however, does not cover the requirements for mechanical expansion anchors, powder-activated nails or studs, and anchor bolts fabricated from deformed bars.
When S1 is not specified, the Grade 55 material satm or may not be weldable.
Steel City Bolt – ASTM F Specification
This abstract is a brief summary of the referenced standard. 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 Permanent grade identification on the end of the anchor bolt that projects from the concrete, in lieu of color coding.
Supplementary requirements shall apply only when specified in the purchase order or contract. Through chemical composition restrictions and by a carbon equivalency formula, S1 provides assurance of weldability.
Color coding on the end — 36 blue, 55 yellow, and red — helps facilitate easy identification in the field. File upload If you have a drawing or photo of your custom product, please upload here. 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 mild steel 36 ksi.
Your email address will not be published. Permanent manufacturer and grade marking is allowed under the S2 supplementary 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 Supplementary requirements shall apply only when specified in the purchase order or contract.
In addition to standard round be… https: If weldability is required, supplementary requirement S1 must be specified. Grade 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.
For additional compatible nuts see the Nut Compatibility Chart. The anchor bolts shall also meet specified values for nominal size, body diameter, bend section, length, bend angle, and coated length. This field should be left blank. All of the grade 55 round bar that Portland Bolt stocks will meet the S1 weldability requirements.
On the other hand, B7 is heat treated, increasing strength but rendering the material more brittle. The purchaser can specify supplemental requirement S1 which requires weldability through chemical composition restrictions and by a carbon equivalency formula. Welding Contrary to popular belief, not all grade 55 material is weldable. 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.
Washers are detailed in 6. References to anchor bolts in this standard do not necessarily exclude all-thread rod. We are a prime U.
